-.SH "SYNOPSIS"
-.IX Header "SYNOPSIS"
-This document is the Table of Contents for \s-1XPA\s0.
-.SH "DESCRIPTION"
-.IX Header "DESCRIPTION"
-The \s-1XPA\s0 messaging system provides seamless communication between many
-kinds of Unix programs, including X programs and Tcl/Tk programs.  It
-also provides an easy way for users to communicate with XPA-enabled
-programs by executing \s-1XPA\s0 client commands in the shell or by utilizing
-such commands in scripts.  Because \s-1XPA\s0 works both at the programming
-level and the shell level, it is a powerful tool for unifying any
-analysis environment: users and programmers have great flexibility in
-choosing the best level or levels at which to access \s-1XPA\s0 services, and
-client access can be extended or modified easily at any time.
-.PP
-A program becomes an XPA-enabled server by defining named points of
-public access through which data and commands can be exchanged with
-other client programs (and users).  Using standard \s-1TCP\s0 sockets as a
-transport mechanism, \s-1XPA\s0 supports both single-point and broadcast
-messaging to and from these servers.  It supports direct communication
-between clients and servers, or indirect communication via an
-intermediate message bus emulation program. Host-based access control
-is implemented, as is as the ability to communicate with \s-1XPA\s0 servers
-across a network.
-.PP
-\&\s-1XPA\s0 implements a layered interface that is designed to be useful both
-to software developers and to users.  The interface consists of a
-library of \s-1XPA\s0 client and server routines for use in C/\*(C+ programs and
-a suite of high-level user programs built on top of these libraries.
-Using the \s-1XPA\s0 library, access points can be added to Tcl/Tk programs,
-Xt programs, or to Unix programs that use the \s-1XPA\s0 event loop or any
-event loop based on \fIselect()\fR.  Client access subroutines can be added
-to any Tcl/Tk, Xt, or Unix program. Client access also is supported at
-the command line via a suite of high-level programs.

-.SH "NAME"
-\&\fBXPAAcl: Access Control for \s-1XPA\s0 Messaging\fR
-.SH "SYNOPSIS"
-.IX Header "SYNOPSIS"
-\&\s-1XPA\s0 supports host-based access control for each \s-1XPA\s0 access point.  You
-can enable/disable access control using the \s-1XPA_ACL\s0 environment
-variable. You can specify access to specific \s-1XPA\s0 access points for
-specific machines using the \s-1XPA_DEFACL\s0 and \s-1XPA_ACLFILE\s0 environment
-variables. By default, an \s-1XPA\s0 access point is accessible only to
-processes running on the same machine (same as X Windows).
-.SH "DESCRIPTION"
-.IX Header "DESCRIPTION"
-When \s-1INET\s0 sockets are in use (the default, as specified by the
-\&\fI\s-1XPA_METHOD\s0\fR environment variable), \s-1XPA\s0 supports a host-based
-access control mechanism for individual access points. This mean that
-access can be specified for get, set, or info operations for each
-access point on a machine by machine basis.  For \s-1LOCAL\s0 sockets, access
-is restricted (by definition) to the host machine.
-.PP
-\&\s-1XPA\s0 access control is enabled by default, but can be turned off by
-setting the \fI\s-1XPA_ACL\s0\fR environment variable to \fIfalse\fR.
-In this case, any process can access any \s-1XPA\s0 server.
-.PP
-Assuming that access control is turned on, the \s-1ACL\s0 for an individual
-\&\s-1XPA\s0 access point is set up when that access point is registered
-(although it can be changed later on; see below). This can be done in
-one of two ways:
-.PP
-Firstly, the \fI\s-1XPA_ACLFILE\s0\fR environment variable can defined to
-point to a file of access controls for individual access points. The format
-of this file is:
-.PP
-.Vb 1
-\& class:name ip acl
-.Ve
-.PP
-The first argument is a template that specifies the class:name of the
-access point covered by this \s-1ACL\s0. See
-\&\s-1XPA\s0 Access Points and Templates
-for more information about xpa templates.
-.PP
-The second argument is the \s-1IP\s0 address (in human-readable format) of
-the machine which is being given access.  This argument can be
-\&\fI*\fR to match all \s-1IP\s0 addresses.  It also can be \fI\f(CI$host\fI\fR
-to match the \s-1IP\s0 address of the current host.
-.PP
-The third argument is a string combination of \fIs\fR, \fIg\fR,
-or \fIi\fR to allow \fIxpaset\fR, \fIxpaget\fR, or
-\&\fIxpainfo\fR access respectively.  The \s-1ACL\s0 argument can be
-\&\fI+\fR to give \fIsgi\fR access or it can be \fI\-\fR to turn
-off all access.
-.PP
-For example,
-.PP
-.Vb 3
-\&  *:xpa1  somehost sg
-\&  *:xpa1  myhost +
-\&  * * g
-.Ve
-.PP
-will allow processes on the machine somehost to make xpaget and xpaset calls,
-allow processes on myhost to make any call, and allow all other hosts to
-make xpaget (but not xpaset) calls.
-.PP
-Secondly, if the \fI\s-1XPA_ACLFILE\s0\fR does not exist, then a single
-default value for all access points can be specified using the
-\&\fI\s-1XPA_DEFACL\s0\fR environment variable.  The default value for this
-variable is:
-.PP
-.Vb 1
-\&  #define XPA_DEFACL "*:* $host +"
-.Ve
-.PP
-meaning that all access points are fully accessible to all processes
-on the current host. Thus, in the absence of any \s-1ACL\s0 environment variables,
-processes on the current host have full access to all access points
-created on that host. This parallels the X11 xhost mechanism.
-.PP
-Access to an individual \s-1XPA\s0 access point can be changed using the \-acl
-parameter for that access point.  For example:
-.PP
-.Vb 1
-\&  xpaset \-p xpa1 \-acl "somehost \-"
-.Ve
-.PP
-will turn off all access control for somehost to the xpa1 access point, while:
-.PP
-.Vb 1
-\&  xpaset \-p XPA:xpa1 \-acl "beberly gs"
-.Ve
-.PP
-will give beberly xpaget and xpaset access to the access point whose
-class is \s-1XPA\s0 and whose name is xpa1.
-.PP
-Similarly, the current \s-1ACL\s0 for a given access point can be retrieved using:
-.PP
-.Vb 1
-\&  xpaget xpa1 \-acl
-.Ve
-.PP
-Of course, you must have xpaget access to this \s-1XPA\s0 access point to
-retrieve its \s-1ACL\s0.
-.PP
-Note that the \s-1XPA\s0 access points registered in the \fIxpans\fR
-program also behave according to the \s-1ACL\s0 rules.  That is, you cannot

-.SH "NAME"
-\&\fBXPACode: Where to Find Example/Test Code\fR
-.SH "SYNOPSIS"
-.IX Header "SYNOPSIS"
-The \s-1XPA\s0 source code directory contains two test programs,
-\&\fIstest.c\fR, and \fIctest.c\fR that can serve as
-examples for writing \s-1XPA\s0 servers and clients, respectively.
-They also can be used to test various features of \s-1XPA\s0.
-.SH "DESCRIPTION"
-.IX Header "DESCRIPTION"
-To build the \s-1XPA\s0 test programs, execute:
-.PP
-.Vb 1
-\&   make All
-.Ve
-.PP
-in the \s-1XPA\s0 source directory to generate the \fIstest\fR and
-\&\fIctest\fR programs.  (\s-1NB:\s0 this should work on all platforms,
-although we have had problems with unresolved externals on one
-Sun/Solaris machine, for reasons still unknown.)
-.PP
-The stest program can be executed with no arguments to start
-an \s-1XPA\s0 server that contains the access points: xpa, xpa1,
-c_xpa (containing sub-commands cmd1 and cmd2), and i_xpa.
-You then can use xpaset and xpaget to interact with these access points:
-.PP
-.Vb 4
-\&  cat xpa.c | xpaset xpa      # send to xpa
-\&  cat xpa.c | xpaset "xpa*"   # send to xpa and xpa1
-\&  xpaget xpa                  # receive from xpa
-\&  xpaget xpa*                 # receive from xpa and xpa1
-.Ve
-.PP
-etc. You also can use ctest to do the same thing, or to iterate:
-.PP
-.Vb 4
-\&  ctest \-s \-l 100 xpa        # send to xpa 100 times
-\&  ctest \-s \-l 100 "xpa*"     # send to xpa and xpa1 100 times
-\&  ctest \-g \-l 100 xpa        # receive from xpa 100 times
-\&  ctest \-g \-l 100 "xpa*"     # receive from xpa and xpa1 100 times
-.Ve
-.PP
-More options are available: see the stest.c and ctest.c code itself, which
-were used extensively to debug \s-1XPA\s0.
-.PP
-The file test.tcl in the \s-1XPA\s0 source directory gives examples for using the 
-XPATclInterface.

-.SH "DESCRIPTION"
-.IX Header "DESCRIPTION"
-You can find out which \s-1XPA\s0 access points have been registered with

-\&\s-1XPA\s0 name server
-by executing the

-command to retrieve info from the \s-1XPA\s0 name server:
-.PP
-.Vb 1

-.Ve
-.PP
-If, for example, the

-.PP
-.Vb 4

-.Ve
-.PP
-Note that access to this information is subject to the usual
-\&\s-1XPA\s0 Access Control restrictions.
-.PP
-Each \s-1XPA\s0 access point supports a number of reserved sub-commands that provide
-access to different kinds of information, e.g. the access control for
-that access point.  These sub-commands can be executed by using
-xpaset
-or
-xpaget
-at the command line, or
-\&\fIXPAGet()\fR
-or
-\&\fIXPASet()\fR
-in programs, e.g:
-.PP
-.Vb 3

-\&  xpaget ds9 \-help
-\&  xpaget ds9 env FOO
-\&
-\&  xpaset \-p ds9 env FOO foofoo
-.Ve
-.PP
-With the exception of \fB\-help\fR and \fB\-version\fR, reserved
-sub-commands are available only on the machine on which the \s-1XPA\s0 server
-itself is running.
-.PP
-The following reserved sub-commands are defined for all access points:
-.IP "\(bu" 4
-\&\fB\-acl\fR get (set) the access control list [options: host type acl, for set]
-.Sp
-The 'xpaset' option allows you to add a new acl for a given host, or change
-the acl for an existing host. See
-\&\s-1XPA\s0 Access Control
-for more information.
-This access point is available only on the server machine.
-.IP "\(bu" 4
-\&\fB\-env\fR get (set) an environment variable [options: name (value, for set)]
-.Sp
-The 'xpaget' option will return the value of the named environment
-variable.  The 'xpaset' option will set the value of the names
-variable to the specified value.
-This access point is available only on the server machine.
-(Please be advised that we have had problems setting environment
-variables in static Tcl/Tk programs such as ds9 running under Linux.)
-.IP "\(bu" 4
-\&\fB\-clipboard\fR set(get) information on a named clipboard
-.Sp
-Clients can store \s-1ASCII\s0 state information on any number of named
-clipboards. Clipboards of the same name created by clients on
-different machines are kept separate.  The syntax for creating a
-clipboard is:
-.Sp
-.Vb 2
-\&  [data] | xpaset [server] \-clipboard add|append [clipboard_name]
-\&  xpaset \-p [server] \-clipboard delete [clipboard_name]
-.Ve
-.Sp
-Use \*(L"add\*(R" to create a new clipboard or replace the contents of an existing
-one. Use \*(L"append\*(R" to append to an existing clipboard.
-.Sp
-Information on a named clipboard is retrieved using:
-.Sp
-.Vb 1
-\&  xpaget [server] \-clipboard [clipboard_name]
-.Ve
-.IP "\(bu" 4
-\&\fB\-exec\fR set: execute commands from buffer [options: none]
-.Sp
-If \-exec is specified in the paramlist of an 'xpaset' call, then further
-sub-commands will be retrieved from the data buffer.
-.IP "\(bu" 4
-\&\fB\-help\fR get: return help string for this \s-1XPA\s0 or sub-command [options: name (for sub\-commands)]
-.Sp
-Each \s-1XPA\s0 access point and each \s-1XPA\s0 sub-command can have a help string
-associated with it that is specified when the access point is defined.
-The \-help option will return this help string.  For \s-1XPA\s0 access points
-that contain user-defined sub-commands, you can get the help string
-for a particular sub-command by specifying its name, or else get the
-help strings for all sub-commands if not name is specified.
-.IP "\(bu" 4
-\&\fB\-ltimeout\fR get (set) the long timeout value [options: seconds|reset]
-.Sp
-The 'xpaget' option will return the value of the long timeout (in seconds).
-The 'xpaset' option will set the value of the long timeout. If \*(L"reset\*(R" is
-specified, then the timeout value will be reset to the default value.
-.IP "\(bu" 4
-\&\fB\-nsconnect\fR set: re-establish name server connection to all \s-1XPA\s0's [options: none]
-.Sp
-If the 
-\&\s-1XPA\s0 Name Server (xpans)
-process has terminated unexpectedly and then re-started, this
-sub-command can be used to re-establish the connection.  You use it by
-sending the command to the [name:port] or [file] of the access point
-instead of to the \s-1XPA\s0 name (since the latter requires the xpans
-connection!):
-.Sp
-.Vb 1
-\&  xpaset \-p 838e2f67:1268 \-nsconnect
-.Ve
-.Sp
-See xpans for more information.
-.IP "\(bu" 4
-\&\fB\-nsdisconnect\fR set: break name server connection to all \s-1XPA\s0's [options: none]
-.Sp
-This sub-command will terminate the connection to the
-\&\s-1XPA\s0 Name Server (xpans), thereby making
-all access points inaccessible except through their underlying [name:port]
-or [file] identifiers.  I forget why we added it, it seems pretty useless.
-.IP "\(bu" 4
-\&\fB\-stimeout\fR get (set) the short timeout value [options: seconds|reset]
-.Sp
-The 'xpaget' option will return the value of the short timeout (in seconds).
-The 'xpaset' option will set the value of the short timeout. If \*(L"reset\*(R" is
-specified, then the timeout value will be reset to the default value.
-.IP "\(bu" 4
-\&\fB\-remote\fR set: register xpa with remote server [options: host[:port] [acl]] [\-proxy]
-.Sp
-This sub-command will register the \s-1XPA\s0 access point with the \s-1XPA\s0 name
-server (xpans) on the specified host (which must already be running).
-The specified host also is given access control to the access point,
-using the specified acl or the default acl of \*(L"+\*(R" (meaning the remote
-host can xpaset, xpaget, xpainfo or xpaaccess). If the acl is
-specified as \*(L"\-\*(R", then the access point is unregistered. 
-See Communication Between Machines
-for more information on how this sub-command is used.
-.IP "\(bu" 4
-\&\fB\-version\fR get: return \s-1XPA\s0 version string [options: none]
-.Sp
-The version refers to the version of \s-1XPA\s0 used to define this access point
-(currently something like 2.0).
-.PP
-You can add your own reserved commands to all \s-1XPA\s0 access points by using the

-routine, passing the \s-1XPA\s0 handle returned by \fI\s-1XPA\s0 XPAGetReserved(void)\fR

-.SH "DESCRIPTION"
-.IX Header "DESCRIPTION"
-The following are tips for converting from xpa 1.0 (Xt-based xpa) to
-xpa 2.0 (socket-based xpa). The changes are straight-forward and
-almost can be done automatically (we used editor macros for most of
-the conversion).
-.IP "\(bu" 4
-The existence of the cpp \s-1XPA_VERSION\s0 directive to distinguish between 1.0
-(where it is not defined) and 2.0 (where it is defined).
-.IP "\(bu" 4
-Remove the first widget argument from all send and receive server
-callbacks.  Also change first 2 arguments from XtPointer to void
-*. For example:
-.Sp
-#ifdef \s-1XPA_VERSION\s0
-static void XPAReceiveFile(client_data, call_data, paramlist, buf, len)
-     void *client_data;

-static void XPAReceiveFile(w, client_data, call_data, paramlist, buf, len)
-     Widget w;
-     XtPointer client_data;
-     XtPointer call_data;
-     char *paramlist;
-     char *buf;
-     int len;
-#endif
-.IP "\(bu" 4
-Server callbacks should be declared as returning int instead
-of void. They now should return 0 for no errors, \-1 for error.
-.IP "\(bu" 4
-The mode flags have changed when defining \s-1XPA\s0 server callbacks.
-The old \fIS\fR flag (save buffer) is replaced by \fIfreebuf=false\fR.

-.SH "NAME"
-\&\fBXPAEnv: Environment Variables for \s-1XPA\s0 Messaging\fR
-.SH "SYNOPSIS"
-.IX Header "SYNOPSIS"
-Describes the environment variables which can be used to tailor the overall
-\&\s-1XPA\s0 environment.
-.SH "DESCRIPTION"
-.IX Header "DESCRIPTION"
-The following environment variables are supported by \s-1XPA:\s0
-.IP "\(bu" 4
-\&\fB\s-1XPA_ACL\s0\fR
-.Sp
-If \fI\s-1XPA_ACL\s0\fR is \fItrue\fR, then 
-host-based \s-1XPA\s0 Access Control
-is turned on and only specified machines can access specified access
-points.  If \fIfalse\fR, then access control is turned off and any
-machine can access point. The default is turn turn access control on.
-.IP "\(bu" 4
-\&\fB\s-1XPA_ACLFILE\s0\fR
-.Sp
-If
-\&\s-1XPA\s0 Access Control
-is turned on, this variable specifies the name of the file containing
-access control information for all access points started by this user.
-The default file name is: \fI\f(CI$HOME\fI/acls.xpa\fR.
-.IP "\(bu" 4
-\&\fB\s-1XPA_CONNECT_TIMEOUT\s0\fR
-.Sp
-When an \s-1XPA\s0 server first starts up, it immediately tries to
-connect to the \s-1XPA\s0 name server program (xpans) on the host specified by
-the \fI\s-1XPA_NSINET\s0\fR variable. (If this connection fails on the
-local host, and if xpans can be found in the path, then the name
-server is started automatically.)  Unfortunately, a mis-configured
-network can cause this connect attempt to hang for many seconds while
-the \fIconnect()\fR system call times out. Therefore, an alarm is started
-to interrupt the \fIconnect()\fR call and prevent a long hang.  The initial
-value of the alarm timeout is 10 seconds, but can be changed by setting
-this environment variable. If you want to disable the alarm and allow
-the initial \fIconnect()\fR to time out, set the value of this variable to
-0. Normally, users would not change this variable at all.
-.IP "\(bu" 4
-\&\fB\s-1XPA_CLIENT_DOXPA\s0\fR
-.Sp
-Normally, an \s-1XPA\s0 client (xpaget, xpaset, etc.) will process incoming
-\&\s-1XPA\s0 server requests while awaiting the completion of the client request.
-Setting this variable to \*(L"false\*(R" will prevent \s-1XPA\s0 server requests from
-being processed by the client.
-.IP "\(bu" 4
-\&\fB\s-1XPA_DEFACL\s0\fR
-.Sp
-If
-\&\s-1XPA\s0 Access Control
-is turned on, this variable specifies the default access control
-condition for all access points, if the \fI\s-1XPA_ACLFILE\s0\fR file does
-not exist.  The default acl is: \fI\f(CI$host:\fI* \f(CI$host\fI +\fR, meaning that
-all processes on the host machine have full access to all access points.
-.IP "\(bu" 4
-\&\fB\s-1XPA_HOST\s0\fR
-.Sp
-For the \s-1INET\s0 socket method, \s-1XPA\s0 utilizes the canonical hostname (as
-returned by the \fIgethostname()\fR routine) to construct the \s-1IP\s0 part of the
-method id. Under some circumstances, this might not be a correct choice
-of name and \s-1IP\s0. For example, if an \s-1XPA\s0 server is started on a machine
-running \s-1VPN\s0, you might want to use the \s-1VPN\s0 name and \s-1IP\s0 instead of the
-canonical host name, so that other machines in the \s-1VPN\s0 network can
-access the server. In this case, you can set the \s-1XPA_HOST\s0 to be
-the \s-1VPN\s0 name (if resolvable) or, more easily, the \s-1VPN\s0 \s-1IP\s0.
-.IP "\(bu" 4
-\&\fB\s-1XPA_IOCALLSXPA\s0\fR
-.Sp
-Setting this variable causes all \s-1XPA\s0 socket \s-1IO\s0 calls to process
-outstanding \s-1XPA\s0 requests whenever the primary socket is not ready for
-\&\s-1IO\s0. This means that a server making a client call will (recursively)
-process incoming server requests while waiting for client completion.
-This inter-IO \s-1XPA\s0 processing avoids a rare
-\&\s-1XPA\s0 Race Condition: two or more
-\&\s-1XPA\s0 servers sending messages to one another using an \s-1XPA\s0 client
-routine such as \fIXPASet()\fR can deadlock while each waits for the other
-server to respond. This can happen, for example, if the servers call
-\&\fIXPAPoll()\fR with a time limit, and send messages in between the polling call.
-.Sp
-By default, this option is turned off, because we judge that the added
-code complication and overhead involved will not be justified by the
-amount of its use.  Moreover, processing \s-1XPA\s0 requests within socket \s-1IO\s0
-can lead to non-intuitive results, since incoming server requests will
-not necessarily be processed to completion in the order in which they
-are received.
-.IP "\(bu" 4
-\&\fB\s-1XPA_LOGNAME\s0\fR
-.Sp
-\&\s-1XPA\s0 preferentially uses the de facto standard environment variable
-\&\s-1LOGNAME\s0 to determine the username when registering an access point in
-the name server. If this environment variable has been used for
-something other than the actual user name (such as a log file name),
-unexpected results can ensue. In such cases, use the \s-1XPA_LOGNAME\s0
-variable to set the user name. (If neither exists, then getpwuid(\fIgeteuid()\fR)
-is used as a last resort).
-.IP "\(bu" 4
-\&\fB\s-1XPA_LONG_TIMEOUT\s0\fR
-.Sp
-\&\s-1XPA\s0 is designed to allow data to be sent from one process to
-another over a long period of time (i.e., a program that generates
-image data sends that data to an image display, but slowly) but it
-also seeks to prevent hangs. This is done by supporting 2 timeout
-periods: a \fIshort\fR timeout for protocol communication
-and a \fIlong\fR for data communication.
-.Sp
-The \fI\s-1XPA_LONG_TIMEOUT\s0\fR variable controls the \fIlong\fR
-timeout and is used to prevent hangs in cases where communication
-between the client and server that is \fInot\fR controlled by the
-\&\s-1XPA\s0 interface itself. Transfer of data between client and server, or a
-client's wait for a status message after completion of the server
-callback, are two examples of this sort of communication. By default,
-the \fIlong\fR timeout is set to 180 seconds.
-Setting the value to \-1 will disable \fIlong\fR timeouts and allow
-an infinite amount of time.
-.IP "\(bu" 4
-\&\fB\s-1XPA_MAXHOSTS\s0\fR
-.Sp
-The maximum number of access points that the programs 
-\&\fIxpaset\fR, \fIxpaget\fR, and \fIxpainfo\fR will
-communicate with at one time. The default is 64, meaning, for
-example, that the \fIxpaset\fR program will not send a message
-to more than 100 access points at one time and \fIxpaget\fR will
-not retrieve from more than 100 access points at one time.
-.IP "\(bu" 4
-\&\fB\s-1XPA_METHOD\s0\fR
-.Sp
-Determines the socket connection method used by this session of \s-1XPA\s0.
-The choices are: \fIinet\fR (to use \s-1INET\s0 or Internet-based
-sockets), \fIlocalhost\fR (to use the machines localhost inet
-socket), or \fIlocal (unix)\fR (to use \s-1UNIX\s0 sockets). The default
-is \fI\s-1INET\s0\fR.  Using the \fIinet\fR method will allow access
-from other machines (subject to access controls) but using
-\&\fIlocalhost\fR or \fIlocal\fR will not. Localhost is most useful
-for private access and when the machine in question is not connected
-to the Internet. The unix method also can be used for private access
-and non-Internet connections (Unix platforms only).
-.Sp
-Once defined, the first registration of an \s-1XPA\s0 access point will
-ensure that an instance of the
-\&\s-1XPA\s0 Name Server (xpans)
-is running that handles that connection method. All new access points
-will use the new connection method but existing access points will use
-the original method.
-.IP "\(bu" 4
-\&\fB\s-1XPA_NSINET\s0\fR
-.Sp
-For the \fIinet\fR method of socket connection, this variable
-specifies the host and port on which the 
-\&\s-1XPA\s0 Name Server (xpans)
-is listens for new access points. The default is \fI\f(CI$host:\fI$port\fR,
-meaning that the default \s-1XPA\s0 port (14285) on the current machine
-(as returned by \fIgethostname()\fR) is used. If several machines were all
-accessing the same \s-1XPA\s0 access points, you would use this variable to
-specify that they all use the same name server to find out about these
-access points.  For example, a value of \fImyhost:$port\fR would
-mean that the xpans name server is running on myhost and uses the
-default port 12345.  All machines would then get the \s-1XPA\s0 access points
-registered with that name server, subject to access controls.
-.Sp
-The port used by xpans to register its \s-1XPA\s0 access point normally is
-taken to be one greater than the port on which it receives new access
-points from \s-1XPA\s0 servers. You can specify a specific access point port
-using the syntax machine:port1,port2, i.e., the access point port is
-specified after the comma.  For example, \f(CW$host:12345\fR,23456 will listen
-for new access ports on 12345 and will accept \s-1XPA\s0 commands on 23456.
-.IP "\(bu" 4
-\&\fB\s-1XPA_NSREGISTER\s0\fR
-.Sp
-This boolean variable specifies whether a server registers its \s-1XPA\s0
-access point with the specified xpans name server. The default is
-\&\fItrue\fR.  If set to \fIfalse\fR, the access point still is
-set up but it is not registered with xpans and therefore cannot be
-accessed by name. (It can be accessed by method, if the latter is
-known.) Note that an access point can be registered later on (using
-\&\-remote or \-proxy, for example). This variable mainly is useful in
-cases where the Internet configuration is broken (so that registration
-causes a \s-1DNS\s0 hang) but you still wish to and can use the server with a
-remote xpans (e.g., ds9's Virtual Observatory capability).
-.IP "\(bu" 4
-\&\fB\s-1XPA_NSUNIX\s0\fR
-.Sp
-For the \fIlocal\fR method of socket connection, this variable
-specifies the name of the Unix file that will be used to access the
-\&\s-1XPA\s0 Name Server (xpans). The default is
-\&\fIxpans_unix\fR. This variable is not usually needed. Note that
-is the \fIlocal\fR socket method is used, then remote machines will
-not be able to access the xpans name server or the registered \s-1XPA\s0 access
-points.
-.IP "\(bu" 4
-\&\fB\s-1XPA_NSUSERS\s0\fR
-.Sp
-This variable specifies whether other users' access points will be
-returned by the
-\&\s-1XPA\s0 Name Server (xpans) for use by
-\&\fIxpaget\fR, \fIxpaset\fR, etc.
-Generally speaking, it is sufficient to run one xpans name server per
-machine and register the access points for all users with that xpans.
-This means, for example, that if you request information from
-ds9 by running:
-.Sp
-.Vb 1
-\&  xpaget ds9 colormap
-.Ve
-.Sp
-you might get information from your own ds9 as well as
-from another user running ds9 on the same machine.  The
-\&\fI\s-1XPA_NSUSERS\s0\fR variable controls whether you want such access 
-to the access points of other users.
-By default, only your own access points are returned, so
-that, in the example above, you would only get the colormap information
-from the ds9 you registered. If, however, you had set the value of the
-\&\fI\s-1XPA_NSUSERS\s0\fR variable to \fIeric,fred\fR, then you would be
-able to communicate with both eric and fred's access points. Note that
-this variable can be overridden using the \fI\-u\fR switch on the
-\&\fIxpaget\fR, \fIxpaset\fR, and \fIxpainfo\fR programs.
-.IP "\(bu" 4
-\&\fB\s-1XPA_PORT\s0\fR
-.Sp
-A semi-colon delimited list of user specified ports to use for specific
-\&\s-1XPA\s0 access points. The format is each specification is:
-.Sp
-class:template port1[ port2]
-.Sp
-where \fBport1\fR is the main (command) port for the access point and
-\&\fBport2\fR is the (secondary) data port. If port2 is not specified,
-it defaults to a value of 0 (meaning the system assigns the port).
-.Sp
-Specification of specific ports is useful, for example, when a machine
-outside a firewall needs to communicate with a machine inside a
-firewall. In such a case, the firewall should be configured to allow
-socket connections to both the command and data port from the outside
-machine, and the inside \s-1XPA\s0 program should be started up with the
-outside machine in its \s-1ACL\s0 list. Then, when the inside program is
-started with specified ports, outside \s-1XPA\s0 programs can use
-\&\*(L"machine:port\*(R" to contact the inside access points, instead of the
-access point names. That is, the machine outside the firewall does not
-need access to the \s-1XPA\s0 name server:
-.Sp
-export XPA_PORT=\*(L"DS9:ds9 12345 12346\*(R"   # on machine \*(L"inside\*(R"
-cat foo.fits | xpaset inside:12345 fits # on machine \*(L"outside\*(R"
-.Sp
-Note that 2 ports are required for full \s-1XPA\s0 communication and
-therefore 2 ports should be specified to go through a firewall.  The
-second port assignment is not important if you simply are assigning
-the command port in order to communicate commands with a known
-port (e.g., to bypass the xpans name server). If only one (command)
-port is specified, the system will negotiate a random data port and
-everything will work properly.
-.Sp
-This support is somewhat experimental. If you run into problems, please
-let us know.
-.IP "\(bu" 4
-\&\fB\s-1XPA_PORTFILE\s0\fR
-.Sp
-A list of user-specified port to use for specific xpa access points.
-The format of the file is:
-.Sp
-class:template port1 [port2]
-.Sp
-where \fBport1\fR is the main port for the access point and
-\&\fBport2\fR is the data port. If port2 is not specified, it defaults
-to a value of 0 (meaning the system assigns the port).  See
-\&\fB\s-1XPA_PORT\s0\fR above for an explanation of user-specified ports.
-.IP "\(bu" 4
-\&\fB\s-1XPA_SHORT_TIMEOUT\s0\fR
-.Sp
-\&\s-1XPA\s0 is designed to allow data to be sent from one process to
-another over a long period of time (i.e., a program that generates
-image data sends that data to an image display, but slowly) but it
-also seeks to prevent hangs. This is done by supporting 2 timeout
-periods: a \fIshort\fR timeout for protocol communication
-and a \fIlong\fR for data communication.
-.Sp
-The \fI\s-1XPA_SHORT_TIMEOUT\s0\fR variable
-controls the \fIshort\fR timeout and is used to prevent hangs
-in cases where the \s-1XPA\s0 protocol requires internal communication between
-the client and server that is controlled by the \s-1XPA\s0 interface
-itself. Authentication is an example of this sort of communication,
-as is the establishment of a data channel between the two processes.
-The default value for the \fIshort\fR is 30 seconds (which is
-a pretty long time, actually). Setting the value to \-1 will disable
-\&\fIshort\fR timeouts and allow an infinite amount of time.
-.IP "\(bu" 4
-\&\fB\s-1XPA_SIGUSR1\s0\fR
-.Sp
-If the value of this variable is \fItrue\fR, then \s-1XPA\s0 will
-catch \s-1SIGUSR1\s0 signals when performing an I/O operation in order to
-curtail that operation. This facility allows users to send a \s-1SIGUSR1\s0
-signal to an \s-1XPA\s0 server if a client is hanging up the server by
-sending or receiving data too slowly (timeouts also can be used \*(-- see
-above). When enabled in this way, the \s-1SIGUSR1\s0 signal is ignored at all other
-times, so that its safe to send the signal at any time.  If the
-variable is set to \fIfalse\fR, then \s-1SIGUSR1\s0 is not used at
-all. Turning off \s-1SIGUSR1\s0 would be desired in cases there the program
-uses \s-1SIGUSR1\s0 for some other reason and does not want \s-1XPA\s0 interfering.
-The default is to use the signal.
-.IP "\(bu" 4
-\&\fB\s-1XPA_TIMESTAMP_ERRORS\s0\fR
-.Sp
-If \fI\s-1XPA_TIMESTAMP_ERRORS\s0\fR is \fItrue\fR, then error
-messages will include a date/time string.  This can be useful when
-\&\s-1XPA\s0 errors are being saved in an error log (e.g. Web/CGI use). The
-default is false.
-.IP "\(bu" 4
-\&\fB\s-1XPA_TMPDIR\s0\fR
-.Sp
-This variable specifies the directory into which \s-1XPA\s0 logs, Unix
-socket files (when \fI\s-1XPA_METHOD\s0\fR is \fIlocal\fR), etc. are
-stored. The default is \fI/tmp/.xpa\fR.
-.IP "\(bu" 4
-\&\fB\s-1XPA_VERBOSITY\s0\fR
-.Sp
-Specify the verbosity level of error messages. If the value is
-set to \fI0\fR, \fIfalse\fR, or \fIoff\fR, then no error
-messages are printed to stderr.  If the value is \fI1\fR, then
-important \s-1XPA\s0 error messages will be output.  If the value is
-set to \fI2\fR, \s-1XPA\s0 warnings about out-of-sync messages will also
-be output.  These latter almost always can be ignored.
-.IP "\(bu" 4
-\&\fB\s-1XPA_VERSIONCHECK\s0\fR
-.Sp
-Specify whether a new access point should check its major and minor \s-1XPA\s0
-version number against the version used by the xpans name server at
-registration time. The default is \fItrue\fR. When checking is
-performed, a warning is issued if the server major version is found to
-be greater than the xpans version. Note that the check is performed
-both by the \s-1XPA\s0 server and by the xpans process and warnings will be
-issued by each.  Also, instead of the values of \fItrue\fR or
-\&\fIfalse\fR, you can give this variable an integer value n. In this
-case, each version checking process (i.e., the XPA-enabled server or
-xpans) will print out a maximum of n warning messages (after which
-version warnings are silently swallowed).
-.Sp
-In general, it is a bad idea to run an XPA-enabled server program
-using a version of \s-1XPA\s0 newer than the basic xpaset, xpaget, xpaaccess,
-xpans programs. This sort of mismatch usually will not work due to
-protocol changes.

-.SH "NAME"
-\&\fBXPAInet: \s-1XPA\s0 Communication Between Hosts\fR
-.SH "SYNOPSIS"
-.IX Header "SYNOPSIS"
-\&\s-1XPA\s0 uses standard inet sockets to support communication between two or
-more host computers.
-.SH "DESCRIPTION"
-.IX Header "DESCRIPTION"
-When the Communication Method is set to
-\&\fBinet\fR (as it is by default), \s-1XPA\s0 can be used to communicate
-between different computers on the Internet.  \s-1INET\s0 sockets utilize the
-\&\s-1IP\s0 address of the given machine and a (usually random) port number to
-communicate between processes on the same machine or between different
-machines on the Internet.  These standard Internet sockets are also
-used by programs such as Netscape, ftp. etc.
-.PP
-\&\s-1XPA\s0 supports a host-based Access Control mechanism
-to prevent unauthorized access of \s-1XPA\s0 access points by other computers
-on the Net.  By default, only the machine on which the \s-1XPA\s0 server is
-running can access \s-1XPA\s0 services. Therefore, setting up communication
-between a local \s-1XPA\s0 server machine and a remote client machine
-requires a two-part registration process:
-.IP "\(bu" 4
-the \s-1XPA\s0 service on the local machine must be made known to the 
-remote machine
-.IP "\(bu" 4
-the remote machine must be given permission to access the local
-\&\s-1XPA\s0 service
-.PP
-Three methods by which this remote registration can be accomplished
-are described below.
-.PP
-\&\fBManual Registration\fR
-.PP
-The first method is the most basic and does not require the remote
-client to have xpans running.  To use it, the local server simply
-gives a remote client machine access to one or more \s-1XPA\s0 access points
-using xpaset and the \fB\-acl\fR sub-command. For example,
-consider the \s-1XPA\s0 test program \*(L"stest\*(R" running on a local machine.  By
-default the access control for the access point named \*(L"xpa\*(R" is
-restricted to that machine:
-.PP
-.Vb 3
-\&  [sh]$ xpaget xpa \-acl
-\&  *:* 123.456.78.910 gisa
-\&  *:* localhost gisa
-.Ve
-.PP
-Using xpaset and the \fB\-acl\fR sub-command, a remote client
-machine can be given permission to perform xpaget, xpaset, xpaaccess,
-or xpainfo operations.  For example, to allow the xpaget operation, the
-following command can be issued on the local machine:
-.PP
-.Vb 1
-\&  [sh]$ xpaset \-p xpa \-acl "remote_machine g"
-.Ve
-.PP
-This results in the following access permissions on the local machine:
-.PP
-.Vb 4
-\&  [sh]$ xpaget xpa \-acl
-\&  XPA:xpa 234.567.89.012 g
-\&  *:* 123.456.78.910 gisa
-\&  *:* localhost gisa
-.Ve
-.PP
-The remote client can now use the local server's xpans name server to
-establish communication with the local \s-1XPA\s0 service. This can be done
-on a call-by-call basis using the \fB\-i\fR switch on xpaset, xpaget, etc:
-.PP
-.Vb 6
-\&  [sh]$ xpaget \-i "local_machine:12345" xpa
-\&  class: XPA
-\&  name: xpa
-\&  method: 88877766:2778
-\&  sendian: little
-\&  cendian: big
-.Ve
-.PP
-Alternatively, the \s-1XPA_NSINET\s0 variable on the remote machine can be
-set to point directly to xpans on the local machine, removing
-the need to override this value each time an \s-1XPA\s0 program is run:
-.PP
-.Vb 7
-\&  [csh]$ setenv XPA_NSINET \*(Aqkarapet:$port\*(Aq
-\&  [csh]$ xpaget xpa
-\&  class: XPA
-\&  name: xpa
-\&  method: 88877766:2778
-\&  sendian: little
-\&  cendian: big
-.Ve
-.PP
-Here, '$port' means to use the default \s-1XPA\s0 name service port (14285).
-not a port environment variable.
-.PP
-Access permission for remote client machines can be stored in a file
-on the local machine pointed to by the \fB\s-1XPA_ACLFILE\s0\fR environment
-variable or using the \fB\s-1XPA_DEFACL\s0\fR environment variable. See <A
-HREF=\*(L"./acl.html\*(R">\s-1XPA\s0 Access Control for more information.
-.PP
-\&\fBRemote Registration\fR
-.PP
-If xpans is running on the remote client machine, then a local xpaset
-command can be used with the \fB\-remote\fR sub-command to
-register the local \s-1XPA\s0 service in the remote name service, while at
-the same time giving the remote machine permission to access the local
-service.  For example, assume again that \*(L"stest\*(R" is running on the
-local machine and that xpans is also running on the remote machine.
-To register access of this local xpa on the remote machine, use 
-the xpaset and the \fB\-remote\fR sub-command:
-.PP
-.Vb 1
-\&  [sh]$ ./xpaset \-p xpa \-remote \*(Aqremote_machine:$port\*(Aq +
-.Ve
-.PP
-To register the local xpa access point on the remote machine with xpaget
-access only, execute:
-.PP
-.Vb 1
-\&  [sh]$ ./xpaset \-p xpa \-remote \*(Aqremote_machine:$port\*(Aq g
-.Ve
-.PP
-Once the remote registration command is executed, the remote client
-machine will have an entry such as the following in its own xpans name
-service:
-.PP
-.Vb 2
-\&  [csh]$ xpaget xpans
-\&  XPA xpa gs 88877766:2839 eric
-.Ve
-.PP
-The xpa access point can now be utilized on the remote machine without
-further setup:
-.PP
-.Vb 6
-\&  [csh]$ xpaget xpa
-\&  class: XPA
-\&  name: xpa
-\&  method: 838e2f68:2839
-\&  sendian: little
-\&  cendian: big
-.Ve
-.PP
-To unregister remote access from the local machine, use the same
-command but with a '\-' argument:
-.PP
-.Vb 1
-\&  [sh]$ xpaset \-p xpa \-remote \*(Aqremote_machine:$port\*(Aq \-
-.Ve
-.PP
-The benefit of using remote registration is that communication with
-remote access points can be mixed with that of other access points
-on the remote machine.  Using Access Point
-Names and Templates, one \s-1XPA\s0 command can be used to send or
-receive messages to the remote and local services.
-.PP
-\&\fB\s-1XPANS\s0 Proxy Registration\fR
-.PP
-The two methods described above are useful when the local and remote
-machines are able to communicate freely to one another. This would be
-the case on most Local Area Networks (LANs) where all machines are
-behind the same firewall and there is no port blocking between
-machines on the same \s-1LAN\s0.  The situation is more complicated when the
-\&\s-1XPA\s0 server is behind a firewall, where outgoing connections are
-allowed, but incoming port blocking is implemented to prevent machines
-outside the firewall from connecting to machines inside the
-firewall. Such incoming port blocking will prevent xpaset and xpaget
-from connecting to an \s-1XPA\s0 server inside a firewall.
-.PP
-To allow locally fire-walled \s-1XPA\s0 services to register with remote
-machines, we have implemented a proxy service within the xpans name
-server. To register remote proxy service, xpaset and the
-\&\fB\-remote\fR sub-command is again used, but with an additional
-\&\fB\-proxy\fR argument added to the end of the command:
-.PP
-.Vb 1
-\&  [sh]$ ./xpaset \-p xpa \-remote \*(Aqremote_machine:$port\*(Aq g \-proxy
-.Ve
-.PP
-Once a remote proxy registration command is executed, the remote
-machine will have an entry such as the following in its own xpans name
-service:
-.PP
-.Vb 2
-\&  [csh]$ xpaget xpans
-\&  XPA xpa gs @88877766:2839 eric
-.Ve
-.PP
-The '@' sign in the name service entry indicates that xpans proxy
-processing is being used for this access point. Other than that, from
-the user's point of view, there is no difference in how this \s-1XPA\s0
-access point is contacted using \s-1XPA\s0 programs (xpaset, xpaget, etc.) or
-libraries:
-.PP
-.Vb 6
-\&  [csh]$ xpaget xpa
-\&  class: XPA
-\&  name: xpa
-\&  method: 88877766:3053
-\&  sendian: little
-\&  cendian: big
-.Ve
-.PP
-Of course, the underlying processing of the \s-1XPA\s0 requests is very much
-different when xpans proxy is involved. Instead of an \s-1XPA\s0 program such
-contacting the \s-1XPA\s0 service directly, it contacts the local xpans.
-Acting as a proxy server, xpans communicates with the \s-1XPA\s0 service
-using the command channel established at registration time. Commands
-(including establishing a new data channel) are sent between xpans and
-the \s-1XPA\s0 service to set up a new message transfer, and then data is fed
-to/from the xpa request, through xpans, from/to the \s-1XPA\s0 service. In
-this way, it can be arranged so that connections between the
-fire-walled \s-1XPA\s0 service and the remote client are always initiated by
-the \s-1XPA\s0 service itself. Thus, incoming connections that would be
-blocked by the firewall are avoided. Note that there is a performance
-penalty for using the xpans/proxy service.  Aside from extra overhead
-to set up proxy communication, all data must be sent through the
-intermediate proxy process.
-.PP
-The xpans proxy scheme requires that the remote client allow the local
-\&\s-1XPA\s0 server machine to connect to the remote xpans/proxy server. If the
-remote client machine also is behind a port-blocking firewall, such
-connections will be disallowed. In this case, the only solution is to
-open up some ports on the remote client machine to allow incoming
-connections to xpans/proxy. Two ports must be opened (for command and
-data channel connections). By default, these two ports are 14285 and
-14287. The port numbers can be changed using the \fB\s-1XPA_NSINET\s0\fR
-environment variable. This variable takes the form:
-.PP
-.Vb 1
-\&  setenv XPA_NSINET machine:port1[,port2[,port3]]
-.Ve
-.PP
-where port1 is the main connecting port, port2 is the \s-1XPA\s0 access port,
-and port3 is the secondary data connecting port. The second and third
-ports are optional and default to port1+1 and port1+2, respectively.
-It is port1 and port3 that must be left open for incoming connections.
-.PP
-For example, to change the port assignments so that xpans listens
-for registration commands on port 12345 and data commands on port 28573:
-.PP
-.Vb 1
-\&  setenv XPA_NSINET myhost:12345
-.Ve
-.PP
-Alternatively, all three ports can be assigned explicitly:
-.PP
-.Vb 1
-\&  setenv XPA_NSINET remote:12345,3000,12346
-.Ve
-.PP
-In this case 12345 and 12346 should be open for incoming connections.
-The \s-1XPA\s0 access port (which need not be open to the outside
-world) is set to 3000.
-.PP
-Finally, note that we currently have no mechanism to cope with
-Internet proxy servers (such as \s-1SOCKS\s0 servers). If an \s-1XPA\s0 service is
-running on a machine that cannot connect directly to outside machines,
-but goes through a proxy server instead, there currently is no way to
-register that \s-1XPA\s0 service with a remote machine.  We hope to implement
-support for \s-1SOCKS\s0 proxy in a future release.

-\&\fBXPAIntro: Introduction to the \s-1XPA\s0 Messaging System\fR
-.SH "SYNOPSIS"
-.IX Header "SYNOPSIS"
-A brief introduction to the \s-1XPA\s0 messaging system, which provides
-seamless communication between all kinds of Unix event-driven
-programs, including X programs, Tcl/Tk programs, and Perl programs.
-.SH "DESCRIPTION"
-.IX Header "DESCRIPTION"
-The \s-1XPA\s0 messaging system provides seamless communication between all
-kinds of Unix programs, including X programs, Tcl/Tk programs, and
-Perl programs.  It also provides an easy way for users to communicate
-with these XPA-enabled programs by executing \s-1XPA\s0 client commands in
-the shell or by utilizing such commands in scripts.  Because \s-1XPA\s0 works
-both at the programming level and the shell level, it is a powerful
-tool for unifying any analysis environment: users and programmers have
-great flexibility in choosing the best level or levels at which to
-access \s-1XPA\s0 services, and client access can be extended or modified
-easily at any time.
-.PP
-A program becomes an XPA-enabled server by defining named points of
-public access through which data and commands can be exchanged with
-other client programs (and users).  Using standard \s-1TCP\s0 sockets as
-a transport mechanism, \s-1XPA\s0 supports both single-point and broadcast
-messaging to and from these servers.  It supports direct communication
-between clients and servers, or indirect communication via an
-intermediate message bus emulation program. Host-based access control
-is implemented, as is as the ability to communicate with \s-1XPA\s0 servers
-across a network.
-.PP
-\&\s-1XPA\s0 implements a layered interface that is designed to be useful both
-to software developers and to users.  The interface consists of a
-library of \s-1XPA\s0 client and server routines for use in programs and a
-suite of high-level user programs built on top of these libraries.
-Using the \s-1XPA\s0 library, access points can be added to
-Tcl/Tk
-programs, 
-Xt
-programs, or to Unix programs that use the \s-1XPA\s0 event loop or any
-event loop based on \fIselect()\fR.  Client access subroutines can be added
-to any Tcl/Tk or Unix program. Client access also is supported at the
-command line via a suite of high-level programs.
-.PP
-The major components of the \s-1XPA\s0 layered interface are:
-.IP "\(bu" 4
-A set of \s-1XPA\s0 server routines, centered on 
-\&\fIXPANew()\fR,
-which are used by \s-1XPA\s0 server programs to tag public access points with
-string identifiers and to register send and receive callbacks for
-these access points.
-.IP "\(bu" 4
-A set of \s-1XPA\s0 client routines, centered on the 
-\&\fIXPASet()\fR
-and
-\&\fIXPAGet()\fR,
-which are used by external client applications to exchange data and
-commands with an \s-1XPA\s0 server.
-.IP "\(bu" 4
-High-level programs, centered on
-xpaset
-and
-xpaget,
-which allow data
-and information to be exchanged with \s-1XPA\s0 server programs from the
-command line and from scripts.  These programs have the command syntax:
-.Sp
-.Vb 2
-\&  [data] | xpaset  [qualifiers ...]
-\&           xpaget  [qualifiers ...]
-.Ve
-.IP "\(bu" 4
-An \s-1XPA\s0 name server program, 
-xpans,
-through which \s-1XPA\s0 access point names are
-registered by servers and distributed to clients.
-.PP
-Defining an \s-1XPA\s0 access point is easy: a server application calls
-\&\fIXPANew()\fR,
-\&\fIXPACmdNew()\fR,
-or the experimental
-\&\fIXPAInfoNew()\fR
-routine to
-create a named public access point.  An \s-1XPA\s0 service can specify \*(L"send\*(R"
-and \*(L"receive\*(R" callback procedures (or an \*(L"info\*(R" procedure in the case
-of \fIXPAInfoNew()\fR) to be executed by the program when an external
-process either sends data or commands to this access point or requests
-data or information from this access point.  Either of the callbacks
-can be omitted, so that a particular access point can be specified as
-read-only, read-write, or write-only.  Application-specific client
-data can be associated with these callbacks.  Having defined one or
-more public access points in this way, an \s-1XPA\s0 server program enters
-its usual event loop (or uses the standard \s-1XPA\s0 event loop).
-.PP
-Clients communicate with these \s-1XPA\s0 public access points
-using programs such as
-xpaget,
-xpaset, and
-xpainfo
-(at the command line),
-or routines such as
-\&\fIXPAGet()\fR,
-\&\fIXPASet()\fR,
-and
-\&\fIXPAInfo()\fR
-within a program.  Both methods require specification of the name of
-the access point.  The xpaget program returns data or other
-information from an \s-1XPA\s0 server to its standard output, while the
-xpaset program sends data or commands from its standard input to an
-\&\s-1XPA\s0 application. The corresponding \s-1API\s0 routines set/get data to/from
-memory, returning error messages and other info as needed.  If a
-template
-is used to specify the access point name (e.g., \*(L"ds9*\*(R"), then
-communication will take place with all servers matching that template.
-.PP
-Please note that \s-1XPA\s0 currently is not thread-safe. All \s-1XPA\s0 calls must be
-in the same thread.

-\&\fBXPAMethod: \s-1XPA\s0 Communication Methods\fR
-.SH "SYNOPSIS"
-.IX Header "SYNOPSIS"
-\&\s-1XPA\s0 supports both inet and unix (local) socket communication.
-.SH "DESCRIPTION"
-.IX Header "DESCRIPTION"
-\&\s-1XPA\s0 uses sockets for communication between processes. It supports
-three methods of socket communication: inet, localhost, and unix. In
-general, the same method should be employed for all \s-1XPA\s0 processes in a
-session and the global environment variable \s-1XPA_METHOD\s0 should be used
-to set up the desired method. By default, the preferred method is
-\&\*(L"inet\*(R", which is appropriate for most users. You can set up a
-different method by typing something like:
-.PP
-.Vb 3
-\&  setenv XPA_METHOD local              # unix csh
-\&  XPA_METHOD=local; export XPA_METHOD  # unix sh, bash, windows/cygwin
-\&  set XPA_METHOD=localhost             # dos/windows
-.Ve
-.PP
-The options for \s-1XPA_METHOD\s0 are: \fBinet\fR, \fBunix\fR (or
-\&\fBlocal\fR), and \fBlocalhost\fR. On Unix machines, this
-environment setup command can be placed in your shell init file
-(.cshrc, .profile, .bashrc, etc.) On Windows platforms, it can be
-placed in your \s-1AUTOEXEC\s0.BAT file (I think!).
-.PP
-By default, \fBinet\fR sockets are used by \s-1XPA\s0. These are the standard
-Internet sockets that are used by programs such as Netscape,
-ftp. etc. Inet sockets utilize the \s-1IP\s0 address of the given machine and
-a (usually random) port number to communicate between processes on the
-same machine or between different machines on the Internet. (Note that
-\&\s-1XPA\s0 has an Access Control mechanism to
-prevent unauthorized access of \s-1XPA\s0 access points by other computers on
-the Net). For users connected to the Internet, this usually is the
-appropriate communication method. For more information about setting
-up \s-1XPA\s0 communication between machines, see
-Communication Between Machines.
-.PP
-In you are using \s-1XPA\s0 on a machine without an Internet connection, then
-inet sockets are not appropriate. In fact, an \s-1XPA\s0 process often will
-hang for many seconds while waiting for a response from the Domain
-Name Service (\s-1DNS\s0) when using inet sockets. Instead of inet sockets,
-users on Unix platforms can also use \fBunix\fR sockets (also known
-as local sockets). These sockets are based on the local file system
-and do not make use of the \s-1DNS\s0. They generally are considered to be
-faster than inet sockets, but they are not implemented under
-Windows. Use local sockets as a first resort if you are on a Unix
-machine that is not connected to the Internet.
-.PP
-Users not connected to the Internet also can use \fBlocalhost\fR
-sockets. These are also inet-type sockets but the \s-1IP\s0 address used for
-the local machine is the \fBlocalhost\fR address, 0x7F000001, instead
-of the real \s-1IP\s0 of the machine. Depending on how sockets are set up for
-a given platform, communication with the \s-1DNS\s0 usually is not required in
-this case (though of course, \s-1XPA\s0 cannot interact with other machines).
-The localhost method will generally work on both Unix and Windows
-platforms, but whether the \s-1DNS\s0 is required or not is subject to
-individual configurations.
-.PP
-A final warning/reminder: if your XPA-enabled server hangs at startup
-time and your \s-1XPA_METHOD\s0 is \fBinet\fR, the problem probably is
-related to an incorrect Internet configuration. This can be confirmed
-by using the \fBunix\fR method or (usually) the \fBlocalhost\fR
-method. You can use these alternate methods if other hosts do not need
-access to the \s-1XPA\s0 server.

-What does \s-1XPA\s0 stand for? Dunno! The \s-1XPA\s0 messaging system originally
-was built on top of the X Window System and \s-1XPA\s0 was the mnemonic for
-\&\fIX Public Access\fR, to emphasize that we were providing public
-access to previously private data and algorithms in Xt programs.  Now
-that \s-1XPA\s0 no longer is tied to X, it can be argued that we ought to
-change the name (how about \s-1SPAM:\s0 simple public access mechanism
-), but \s-1XPA\s0 is in wide-spread use in the astronomical community of
-its birth, and the name has taken on a life of its own. If anyone can
-think of what \s-1XPA\s0 now means, please let us know.
-.PP
-If you think this is bad, consider the \s-1MMT\s0 Telescope on Mount Hopkins,
-Arizona. When first installed twenty years ago, it featured an array
-of six 72\-inch diameter mirrors. from which came its name: the
-\&\fIMultiple Mirror Telescope\fR.  In spring of 1999, these mirrors
-were replaced by a single 21 and 1/2 \-foot diameter primary mirror,
-the largest single-piece glass reflector on the North American
-continent. And now \s-1MMT\s0 stands for ... \s-1MMT\s0!

-.SH "DESCRIPTION"
-.IX Header "DESCRIPTION"
-You can call \fIXPANew()\fR, \fIXPACmdNew()\fR, or \fIXPAInfoNew()\fR within a C
-routine to add C\-based \s-1XPA\s0 server callbacks to a TCL/Tk program that
-uses a Tcl/Tk event loop (either \fIvwait()\fR or the Tk event loop);
-Such a program does not need or want to use the \s-1XPA\s0 event loop.
-Therefore, in order to add \s-1XPA\s0 access points to the Tcl/Tk loop, the
-following routine should be called beforehand:
-.PP
-.Vb 1
-\&  int XPATclAddInput(XPA xpa);
-.Ve
-.PP
-Normally, the xpa argument is \s-1NULL\s0, meaning that all current \s-1XPA\s0
-access points are registered with the event loop.  However, if a
-single \s-1XPA\s0 access point is to be added (i.e., after the event loop is
-started) then the handle of that \s-1XPA\s0 access point can be passed to
-this routine.
-.PP
-The significance of the \s-1XPA/TCL\s0 interface goes beyond the support for
-using \s-1XPA\s0 inside C code. The interface allows you to write \s-1XPA\s0
-servers and to make calls to the \s-1XPA\s0 client interface within the Tcl
-environment using the Tcl language directly. The XPA/Tcl
-interface can be loaded using the following package command:
-.PP
-.Vb 1
-\&  package require tclxpa 2.0
-.Ve
-.PP
-Alternatively, you can load the shared object (called libtclxpa.so ) directly:
-.PP
-.Vb 1
-\&  load .../libtclxpa.so tclxpa
-.Ve
-.PP
-Once the tclxpa package is loaded, you can use Tcl versions of \s-1XPA\s0
-routines to define \s-1XPA\s0 servers or make client \s-1XPA\s0 calls.  The
-interface for these routines is designed to match the Unix \s-1XPA\s0
-interface as nearly as possible.  Please refer to
-\&\s-1XPA\s0 Servers
-and
-\&\s-1XPA\s0 Clients
-for general information about these routines.
-.PP
-The file test.tcl in the \s-1XPA\s0 source directory gives examples for using the 
-XPA/Tcl interface.
-.PP
-The following notes describe the minor differences between the interfaces.
-.PP
-\&\fBXPANew\fR
-.PP
-.Vb 1
-\&  set xpa [xpanew class name help sproc sdata smode rproc rdata rmode]
-.Ve
-.PP
-rproc and sproc routines are routines.  The calling sequence of the
-rproc routine is identical to its C counterpart:
-.PP
-.Vb 1
-\&  proc rec_cb { xpa client_data paramlist buf len } { ... }
-.Ve
-.PP
-The sproc routine, however is slightly different from its C counterpart
-because of the difficulty of passing data back from the callback to C:
-.PP
-.Vb 1
-\&  proc sendcb { xpa client_data paramlist } { ... }
-.Ve
-.PP
-Note that the C\-based server's char **buf and int *len arguments are
-missing from the Tcl callback. This is because we did not know how to
-fill buf with data and pass it back to the C routines for communication
-with the client.  Instead, the Tcl server callback uses the following
-routine to set buf and len:
-.PP
-.Vb 1
-\&  xpasetbuf xpa buf len
-.Ve
-.PP
-where:
-.PP
-.Vb 5
-\&  arg           explanation
-\&  \-\-\-\-\-\-        \-\-\-\-\-\-\-\-\-\-\-
-\&  xpa           the first argument of the server callback
-\&  buf           the data to be returned to the client
-\&  len           data length in bytes, (if absent, use length of the buf object)
-.Ve
-.PP
-When this routine is called, a copy of buf is saved for transmission to
-the client.
-.PP
-The fact that buf is duplicated means that \s-1TCL\s0 server writers might wish to
-perform the I/O directly within the callback, rather than have \s-1XPA\s0 do it
-automatically at the end of the routine.  To do this, set:
-.PP
-.Vb 1
-\&  fillbuf=false
-.Ve
-.PP
-in the xpanew smode and then perform I/O through the Tcl channel
-obtained from:
-.PP
-.Vb 1
-\&  set dchan [xparec $xpa datachan]
-.Ve
-.PP
-where:
-.PP
-.Vb 5
-\&  arg           explanation
-\&  \-\-\-\-\-\-        \-\-\-\-\-\-\-\-\-\-\-
-\&  xpa           the first argument of the server callback
-\&  datachan      literal string "datachan" that returns the data channel
-\&  len           data length in bytes, (if absent, use length of the buf object)
-.Ve
-.PP
-\&\s-1NB:\s0 datachan and cmdchan are not available under Windows. It is
-necessary to use the \*(L"raw\*(R" equivalents: datafd and cmdfd.
-.PP
-The same considerations apply to the rproc for receive servers: a copy
-of the incoming data is generated to pass to the receive callback. This
-copy again can be avoided by using \*(L"fillbuf=false\*(R" in the rmode and then
-reading the incoming data from datachan.
-.PP
-The send and receive callback routines can use the xpaerror and xpamessage
-routines to send errors and messages back to the client.  If you also
-want tcl itself to field an error condition, use the standard return call:
-.PP
-.Vb 1
-\&  return ?\-code c? ?\-errorinfo i? ?\-errorcode ec? string
-.Ve
-.PP
-See the Tcl man page for more info.
-.PP
-\&\fBXPARec\fR
-.PP
-The Tcl xparec procedure supplies server routines with access to information 
-that is available via macros in the C interface:
-.PP
-.Vb 1
-\&  set val [xparec xpa <option>]
-.Ve
-.PP
-where option is: name, class, method, cmdfd, datafd, cmdchan,
-datachan.  Note that two additional identifiers, cmdchan and datachan,
-have been added to to provide Tcl channels corresponding to datafd and
-cmdfd.  (These latter might still be retrieved in Tcl and passed back
-to a C routines.)  An additional option called \*(L"version\*(R" can be used to
-determine the \s-1XPA\s0 version used to build the Tcl interface. Note that
-the standard options require a valid \s-1XPA\s0 handle, but \*(L"version\*(R" does
-not (since it simply reports the value of the \s-1XPA_VERSION\s0 definition
-in the \s-1XPA\s0 source include file).
-.PP
-\&\s-1NB:\s0 datachan and cmdchan are not available under Windows. It is
-necessary to use the \*(L"raw\*(R" equivalents: datafd and cmdfd.
-.PP
-.Vb 12
-\&  macro         explanation
-\&  \-\-\-\-\-\-        \-\-\-\-\-\-\-\-\-\-\-
-\&  class         class of this xpa
-\&  name          name of this xpa
-\&  method        method string (inet or local connect info)
-\&  cmdchan       Tcl channel of command socket
-\&  datachan      Tcl channel of data socket
-\&  cmdfd         fd of command socket
-\&  datafd        fd of data socket
-\&  sendian       endian\-ness of server ("little" or "big")
-\&  cendian       endian\-ness of client ("little" or "big"
-\&  version       XPA version used to build this code
-.Ve
-.PP
-Under Windows, the Tcl event handler cannot automatically sense when an
-\&\s-1XPA\s0 socket is ready for \s-1IO\s0 (i.e. \fITcl_CreateFileHandler()\fR is not available
-under Windows). The Windows Tcl event handler therefore must be awakened
-occasionally for check for \s-1XPA\s0 events. This is done using the standard
-\&\fITcl_SetMaxBlockTime()\fR call. The time parameter is defined in tclloop.c
-and is currently set to 1000 microseconds (1/1000 of a second).
-.PP
-The version option can be used to differentiate between source code versions.
-It was created to support legacy Tcl code that needs to maintain the 2.0.5
-calling sequence for xpaaccess. You can use a version test such as:
-.PP
-.Vb 5
-\&  if [catch { xparec "" version } version] {
-\&    puts "pre\-2.1.0e"
-\&  } else {
-\&    puts [split $version .]
-\&  }

-\&\fBXPATemplate: Access Point Names and Templates\fR
-.SH "SYNOPSIS"
-.IX Header "SYNOPSIS"
-\&\s-1XPA\s0 access points are composed of two parts: a general class and a
-specific name.  Both parts accept template characters so that you
-can send/retrieve data to/from multiple servers at one time.
-.SH "DESCRIPTION"
-.IX Header "DESCRIPTION"
-When \s-1XPA\s0 servers call
-\&\fIXPANew()\fR,
-or
-\&\fIXPACmdNew()\fR
-to define \s-1XPA\s0 access points, they specify a string identifier composed of a
-class and a name. When clients communicate with \s-1XPA\s0 access points,
-they specify which access points to communicate with using
-an identifier of the form:
-.PP
-.Vb 1
-\&  class:name
-.Ve
-.PP
-All registered \s-1XPA\s0 access points that match the specified identifier
-will be available for communication (subject to access control rules,
-etc.)
-.PP
-As of \s-1XPA\s0 2.1.5, the length of both the class and name designations are
-limited to 1024 characters.
-.PP
-The \s-1XPA\s0 class:name identifier actually is a template: it accepts wild
-cards in its syntax, so a single specifier can match more than one \s-1XPA\s0
-access point.  (Note that the class is optional and defaults to \*(L"*\*(R".)
-The allowed syntax for clients to specify the class:name template is
-of the form shown below. (Note that \*(L"*\*(R" is used to denote a generic
-wild card, but other wild cards characters are supported, as described
-below).
-.PP
-.Vb 7
-\&  template      explanation
-\&  \-\-\-\-\-\-\-\-      \-\-\-\-\-\-\-\-\-\-\-
-\&  class:name    exact match of class and name
-\&  name          match any class with this name
-\&  *:name        match any class with this name
-\&  class:*       match any name of this class
-\&  *:*           match any access point
-.Ve
-.PP
-In general, the following wild-cards can be applied to class and name:
-.PP
-.Vb 5
-\&  wildcard      explanation
-\&  \-\-\-\-\-\-\-\-      \-\-\-\-\-\-\-\-\-\-\-
-\&  ?             match any character, but there must be one
-\&  *             match anything, or nothing
-\&  [...]         match an inclusive set
-.Ve
-.PP
-Although the class:name template normally is used to refer to \s-1XPA\s0
-access points, these also can be specified using their individual
-socket identifiers.  For inet sockets, the socket identifier is
-\&\fBip:port\fR, where ip can be the DNS-registered name,
-the \s-1ASCII\s0 \s-1IP\s0 number (e.g. 123.45.67.890) or the hex \s-1IP\s0 number
-(e.g. 838f3a60). For unix sockets, the identifier is the socket file
-name.  These socket identifiers are displayed as the fourth argument
-in the xpans display of registered access points.  For example,
-consider the ds9 program started using inet sockets. The xpans name
-server will register something like this:
-.PP
-.Vb 2
-\&  csh> xpaget xpans
-\&  DS9 ds9 gs saord.harvard.edu:3236 eric
-.Ve
-.PP
-You can access ds9 using ip:3236 in any of the three forms:
-.PP
-.Vb 2
-\&  csh> xpaget saord:3236 file
-\&  /home/eric/data/snr.ev
-\&
-\&  csh> xpaget 123.45.67.890:3236 file
-\&  /home/eric/data/snr.ev
-\&
-\&  csh> xpaget 838f3a60:3236 file
-\&  /home/eric/data/snr.ev
-.Ve
-.PP
-In the case of unix  sockets, the socket identifier is a file:
-.PP
-.Vb 2
-\&  csh> xpaget xpans
-\&  DS9 ds9 gs /tmp/.xpa/DS9_ds9.2631 eric
-\&
-\&  csh> xpaget /tmp/.xpa/DS9_ds9.2631 file
-\&  /home/eric/data/snr.ev
-.Ve
-.PP
-This feature can be useful in distinguishing between multiple
-instances of a program that all have the same class:name designation.

-\&\fBXPAUsers: Distinguishing Users\fR
-.SH "SYNOPSIS"
-.IX Header "SYNOPSIS"
-\&\s-1XPA\s0 normally distinguishes between users on a given host, but it is possible
-to send data to access points belonging to other users.
-.SH "DESCRIPTION"
-.IX Header "DESCRIPTION"
-A single \s-1XPA\s0 name service typically serves all users on a given
-machine.  Two users can register the same \s-1XPA\s0 access points on the
-same machine without conflict, because the user's username is
-registered with each access point and, by default, programs such as
-xpaget and xpaset only process access points of the appropriate user.
-For example:
-.PP
-.Vb 4
-\&  XPA xpa1 gs 838e2f67:1262 eric
-\&  XPA xpa2 gs 838e2f67:1266 eric
-\&  XPA xpa1 gs 838e2f67:2523 john
-\&  XPA xpa2 gs 838e2f67:2527 john
-.Ve
-.PP
-Here the users \*(L"eric\*(R" and \*(L"john\*(R" both have registered the access
-points xpa1 and xpa2. When either \*(L"john\*(R" or \*(L"eric\*(R" retrieves
-information from xpa1, they will process only the access point
-registered in their user name.
-.PP
-If you want to access another user's \s-1XPA\s0 access points on a single
-machine, use the \-u [user] option on xpaset, xpaget, etc. For example,
-if eric executes:
-.PP
-.Vb 1
-\&  xpaget \-u john xpa1
-.Ve
-.PP
-he will access John's xpa1 access point.Use \*(L"*\*(R" to access all users
-on a given machine:
-.PP
-.Vb 1
-\&  xpaget \-u "*" xpa1
-.Ve
-.PP
-Note that the \s-1XPA\s0 Environment Variable
-\&\s-1XPA_NSUSERS\s0 can be used to specify the default list of users to
-process:
-.PP
-.Vb 1
-\&  setenv XPA_NSUSERS "eric,john"
-.Ve
-.PP
-will cause access points from both \*(L"eric\*(R" and \*(L"john\*(R" to be processed
-by default.

-\&\fBXPAXt: the \s-1XPA\s0 Interface to Xt (X Windows)\fR
-.SH "SYNOPSIS"
-.IX Header "SYNOPSIS"
-Describes how \s-1XPA\s0 access points can be added to X Toolkit (Xt) programs.
-.SH "DESCRIPTION"
-.IX Header "DESCRIPTION"
-\&\s-1XPA\s0 supports Xt programs: you can call \fIXPANew()\fR, \fIXPACmdNew()\fR, or
-\&\fIXPAInfoNew()\fR within any C routine to add \s-1XPA\s0 server callbacks to an Xt
-program.  Since an Xt program has its own event loop call (i.e.,
-\&\fIXtAppMainLoop()\fR), it therefore does not need or want to use the \s-1XPA\s0
-even loop.  Thus, in order to add \s-1XPA\s0 access points to the standard Xt
-event loop, the following routine should be called before entering the
-loop:
-.PP
-.Vb 1
-\&  int XPAXtAddInput(XtAppContext app, XPA xpa)
-.Ve
-.PP
-The \fIXPAAddAddInput()\fR routine will add \s-1XPA\s0 access points to the Xt event
-loop by making calls to the standard \fIXtAppAddInput()\fR routine. (If the
-XtAppContext argument is \s-1NULL\s0, then the alternate \fIXtAddInput()\fR routine
-is used instead.)  If the xpa argument is \s-1NULL\s0, then all active \s-1XPA\s0
-access points are added to the loop.  If xpa is not \s-1NULL\s0, then only
-the specified access point is added.  The latter type of call is used
-to add new access points from within a callback, after the program has
-entered the \fIXtAppMainLoop()\fR even loop.
