-.if n .ad l
-.nh
-.SH "NAME"
-XPAAccess: return XPA access points matching
-template (XPA 2.1 and above)
-.SH "SYNOPSIS"
-.IX Header "SYNOPSIS"
-.Vb 1
-\&  #include <xpa.h>
-\&
-\&  int XPAAccess(XPA xpa,
-\&                char *template, char *paramlist, char *mode,
-\&                char **names, char **messages, int n);
-.Ve
-.SH "DESCRIPTION"
-.IX Header "DESCRIPTION"
-The XPAAccess routine returns the public access points that match the
-specified second argument template and
-have the specified access type.
-.PP
-A
-template
-of the form \*(L"class1:name1\*(R" is sent to the
-\&\s-1XPA\s0 name server, which returns a list of at most n matching \s-1XPA\s0
-servers.  A connection is established with each of these servers and
-the paramlist string is passed to the server as the data transfer
-request is initiated. If an \s-1XPA\s0 struct is passed to the call, then the
-persistent connections are updated as described above. Otherwise,
-temporary connections are made to the servers (which will be closed
-when the call completes).
-.PP
-The \fIXPAAccess()\fR routine retrieves names from at most n \s-1XPA\s0 servers
-that match the specified template and that were checked for access
-using the specified mode.  The return string contains both the
-class:name and ip:port.  If a given server returned an error or the
-server callback sends a message back to the client, then the message
-will be stored in the associated element of the messages array.
-\&\s-1NB:\s0 if specified, the name and messages arrays must be of size n or greater.
-.PP
-The returned message string will be of the form:
-.PP
-.Vb 1
-\&  XPA$ERROR error\-message (class:name ip:port)
-.Ve
-.PP
-Note that names of matching registered access points are always
-returned but may not be valid; it is not sufficient to assume that the
-returned number of access points is the number of valid access points.
-Rather, it is essential to check the messages array for error
-messages.  Any string in the messages array is an error message and
-indicated that the associated access point is not available.
-.PP
-For example, assume that a server registers a number of access points
-but delays entering its event loop. If a call to \fIXPAAccess()\fR is made
-before the event loop is entered, the call will timeout (after waiting
-for the long timeout period) and return an error of the form:
-.PP
-.Vb 1
-\&  XPA$ERROR: timeout waiting for server authentication (XPA:xpa1)
-.Ve
-.PP
-The error means that the \s-1XPA\s0 access point has been registered but is
-not yet available (because events are not being processed). When the
-server finally enters its event loop, subsequent calls to \fIXPAAccess()\fR
-will return successfully.
-.PP
-\&\s-1NB:\s0 This routine only works with \s-1XPA\s0 servers built with \s-1XPA\s0 2.1.x and later.
-Servers with older versions of \s-1XPA\s0 will return the error message:
-.PP
-.Vb 1
-\&  XPA$ERROR invalid xpa command in initialization string
-.Ve
-.PP
-If you get this error message, then the old server actually is ready
-for access, since it got to the point of fielding the query! The
-xpaaccess program, for example, ignores this message in order to work
-properly with older servers.
-.PP
-The third argument for \fIXPAAccess()\fR is the type of access and can be
-any combination of:
-.PP
-.Vb 5
-\&  type          explanation
-\&  \-\-\-\-\-\-        \-\-\-\-\-\-\-\-\-\-\-
-\&  g             xpaget calls can be made on this access point
-\&  s             xpaset calls can be made on this access point
-\&  i             xpainfo calls can be made on this access point
-.Ve
-.PP
-The mode string argument is of the form: \*(L"key1=value1,key2=value2,...\*(R"
-The following keywords are recognized:
-.PP
-.Vb 3
-\&  key           value           default         explanation
-\&  \-\-\-\-\-\-        \-\-\-\-\-\-\-\-        \-\-\-\-\-\-\-\-        \-\-\-\-\-\-\-\-\-\-\-
-\&  ack           true/false      true            if false, don\*(Aqt wait for ack from server (after callback completes)
-.Ve
-.PP
-The ack keyword is not very useful, since the server completes the callback
-in order to return the data anyway.  It is here for completion (and perhaps
-for future usefulness).

-When \s-1XPA\s0 is initialized, it allocates a small amount of memory for the
-access control list, temp directory path, and reserved commands. This
-memory is found by valgrind to be \*(L"still reachable\*(R", meaning that \*(L"your
-program didn't free some memory it could have\*(R". Calling the
-\&\fIXPACleanup()\fR routine before exiting the program will free this memory

-\&\fBIntroduction\fR
-.PP
-To use the \s-1XPA\s0 application programming interface, a software developer
-generally will include the xpa.h definitions file:
-.PP
-.Vb 1
-\&  #include <xpa.h>
-.Ve
-.PP
-in the software module that defines or accesses an \s-1XPA\s0 access point and
-then will link against the libxpa.a library:
-.PP
-.Vb 1
-\&  gcc \-o foo foo.c libxpa.a
-.Ve
-.PP
-\&\s-1XPA\s0 has been compiled using both C and \*(C+ compilers.
-.PP
-Client communication with \s-1XPA\s0 public access points generally is
-accomplished using \fIXPAGet()\fR or \fIXPASet()\fR within a program (or xpaget
-and xpaset at the command line).  Both routines require specification
-of the name of the access point.  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.

-Add a command to an \s-1XPA\s0 command access point. The \s-1XPA\s0 argument specifies the
-\&\s-1XPA\s0 struct returned by a call to \fIXPANewCmd()\fR. The name argument is the
-name of the command. The other arguments function identically to the
-arguments in the \fIXPANew()\fR command, i.e., the send_callback and rec_callback
-routines have identical calling sequences to their \fIXPANew()\fR counterparts,
-with the exceptions noted below.
-.PP
-When help is requested for a command access point using:
-.PP
-.Vb 1
-\&  xpaget \-h class:name
-.Ve
-.PP
-all of the command help strings are listed.  To get help for a given
-command, use:
-.PP
-.Vb 1
-\&  xpaget \-h class:name cmd
-.Ve
-.PP
-Also, the acl keyword in the send_mode and receive_mode strings is
-global to the access point, not local to the command.  Thus, the value
-for the acl mode should be the same in all send_mode (or receive_mode)
-strings for each command in a command access point. (The acl for
-send_mode need not be the same as the acl for receive_mode, though).

-.SH "DESCRIPTION"
-.IX Header "DESCRIPTION"
-Create a new \s-1XPA\s0 public access point for commands that will share a
-common identifier class:name. Enter this access point into the \s-1XPA\s0
-name server, so that it can be accessed by external processes.
-\&\fIXPACmdNew()\fR returns an \s-1XPA\s0 struct.
-.PP
-It often is more convenient to have one public access point that can
-manage a number of commands, rather than having individual access
-points for each command. For example, it is easier to command the
-ds9 image display using:
-.PP
-.Vb 3
-\&  echo "colormap I8"   | xpaset ds9
-\&  echo "scale log"     | xpaset ds9
-\&  echo "file foo.fits" | xpaset ds9
-.Ve
-.PP
-then to use:
-.PP
-.Vb 3
-\&  echo "I8"       | xpaset ds9_colormap
-\&  echo "log"      | xpaset ds9_scale
-\&  echo "foo.fits" | xpaset ds9_file
-.Ve
-.PP
-In the first case, the commands remain the same regardless of the
-target \s-1XPA\s0 name.  In the second case, the command names must change
-for each instance of ds9.  That is, if a second instance of ds9
-called \s-1DS9\s0 were running, it would be commanded either as:
-.PP
-.Vb 3
-\&  echo "colormap I8"   | xpaset DS9
-\&  echo "scale log"     | xpaset DS9
-\&  echo "file foo.fits" | xpaset DS9
-.Ve
-.PP
-or as:
-.PP
-.Vb 3
-\&  echo "I8"       | xpaset DS9_colormap
-\&  echo "log"      | xpaset DS9_scale
-\&  echo "foo.fits" | xpaset DS9_file
-.Ve
-.PP
-Thus, in cases where a program is going to manage many commands, it
-generally is easier to define them as commands associated with the
-\&\fIXPACmdNew()\fR routine, rather than as separate access points using
-\&\fIXPANew()\fR.
-.PP
-When \fIXPACmdNew()\fR is called, only the class:name identifier is
-specified.  Each sub-command is subsequently defined using the
-\&\fIXPACmdAdd()\fR routine.

-Remove the specified \s-1XPA\s0 public access point from the name server and
-free all associated storage.  Note that removal from the name server
-happens automatically when the process terminates, so this call is not
-generally needed.  It is used when public access points are being
-defined temporarily and then destroyed when no longer needed.  For
-example, ds9 temporarily creates a public access point when it
-loads a new image for display and destroys it when the image is
-unloaded.

-Retrieve data from one or more \s-1XPA\s0 servers whose class:name identifier
-matches the specified template.
-.PP
-A 
-template
-of the form \*(L"class1:name1\*(R" is sent to the

-servers.  A connection is established with each of these servers and
-the paramlist string is passed to the server as the data transfer
-request is initiated. If an \s-1XPA\s0 struct is passed to the call, then the
-persistent connections are updated as described above. Otherwise,
-temporary connections are made to the servers (which will be closed
-when the call completes).
-.PP
-The \fIXPAGet()\fR routine then retrieves data from at most n \s-1XPA\s0 servers,
-places these data into n allocated buffers and places the buffer
-pointers in the bufs array. The length of each buffer is stored in the
-lens array. A string containing the class:name and ip:port is stored
-in the name array.  If a given server returned an error or the server
-callback sends a message back to the client, then the message will be
-stored in the associated element of the messages array.  \s-1NB:\s0 if
-specified, the name and messages arrays must be of size n or greater.
-.PP
-The returned message string will be of the form:

-.Ve
-.PP
-or
-.PP
-.Vb 1
-\&  XPA$MESSAGE message (class:name ip:port)

-.PP
-Note that when there is an error stored in an messages entry, the
-corresponding bufs and lens entry may or may not be \s-1NULL\s0 and 0
-(respectively), depending on the particularities of the server.
-.PP
-The return value will contain the actual number of servers that were
-processed.  This value thus will hold the number of valid entries in
-the bufs, lens, names, and messages arrays, and can be used to loop
-through these arrays.  In names and/or messages is \s-1NULL\s0, no information is

-The bufs, names, and messages arrays should be freed upon completion (if

-.SH "DESCRIPTION"
-.IX Header "DESCRIPTION"
-Send a short paramlist message to one or more \s-1XPA\s0 servers whose
-class:name identifier matches the specified
-template.
-.PP
-A
-template
-of the form \*(L"class1:name1\*(R" is sent to the
-\&\s-1XPA\s0 name server, which returns a list of at most n matching \s-1XPA\s0
-servers.  A connection is established with each of these servers and
-the paramlist string is passed to the server as the data transfer
-request is initiated. If an \s-1XPA\s0 struct is passed to the call, then the
-persistent connections are updated as described above. Otherwise,
-temporary connections are made to the servers (which will be closed
-when the call completes).
-.PP
-The \fIXPAInfo()\fR routine does not send data from a buf to the \s-1XPA\s0
-servers. Only the paramlist is sent.  The semantics of the paramlist
-is not formalized, but at a minimum is should tell the server how to
-get more information.  For example, it might contain the class:name
-of the \s-1XPA\s0 access point from which the server (acting as a client)
-can obtain more info using XPAGet.
-.PP
-A string containing the class:name and ip:port of each server is
-returned in the name array.  If a given server returned an error or
-the server callback sends a message back to the client, then the
-message will be stored in the associated element of the messages
-array.  The returned message string will be of the form:
-.PP
-.Vb 1
-\&  XPA$ERROR   error\-message (class:name ip:port)
-.Ve
-.PP
-or
-.PP
-.Vb 1
-\&  XPA$MESSAGE message     (class:name ip:port)
-.Ve
-.PP
-The return value will contain the actual number of servers that were
-processed.  This value thus will hold the number of valid entries in
-the names and messages arrays, and can be used to loop through these
-arrays.  In names and/or messages is \s-1NULL\s0, no information is passed back
-in that array.
-.PP
-The following keywords are recognized:
-.PP
-.Vb 3
-\&  key           value           default         explanation
-\&  \-\-\-\-\-\-        \-\-\-\-\-\-\-\-        \-\-\-\-\-\-\-\-        \-\-\-\-\-\-\-\-\-\-\-
-\&  ack           true/false      true            if false, don\*(Aqt wait for ack from server
-.Ve
-.PP
-When ack is false, \fIXPAInfo()\fR will not wait for an error return from the \s-1XPA\s0
-server. This means, in effect, that XPAInfo will send its paramlist string
-to the \s-1XPA\s0 server and then exit: no information will be sent from the server
-to the client. This UDP-like behavior is essential to avoid race
-conditions in cases where \s-1XPA\s0 servers are sending info messages to
-other servers. If two servers try to send each other an info message
-at the same time and then wait for an ack, a race condition will result and
-one or both will time out.

-.IX Header "DESCRIPTION"
-[\s-1NB:\s0 this is an experimental interface, new to \s-1XPA\s0 2.0, whose value
-and best use is evolving.]
-.PP
-A program can register interest in receiving a short message about a
-particular topic from any other process that cares to send such a
-message.  Neither has to be an \s-1XPA\s0 server.  For example, if a user
-starts to work with a new image file called new.fits, she might
-wish to alert interested programs about this new file by sending a
-short message using xpainfo:
-.PP
-.Vb 1
-\&  xpainfo IMAGEFILE /data/new.fits
-.Ve
-.PP
-In this example, each process that has used the \fIXPAInfoNew()\fR call to
-register interest in messages associated with the identifier \s-1IMAGEFILE\s0
-will have its \fIinfo_callback()\fR executed with the following calling
-sequence:
-.PP
-.Vb 4
-\&  int info_cb(void *info_data, void *call_data, char *paramlist)
-\&  {
-\&    XPA xpa = (XPA)call_data;
-\&  }
-.Ve
-.PP
-The arguments passed to this routine are equivalent to those sent in
-the \fIsend_callback()\fR routine.  The main difference is that there is no
-buf sent to the info callback: this mechanism is meant for short
-announcement of messages of interest to many clients.
-.PP
-The mode string is of the form: \*(L"key1=value1,key2=value2,...\*(R"
-The following keywords are recognized:
-.PP
-.Vb 3
-\&  key           value           default         explanation
-\&  \-\-\-\-\-\-        \-\-\-\-\-\-\-\-        \-\-\-\-\-\-\-\-        \-\-\-\-\-\-\-\-\-\-\-
-\&  acl           true/false      true            enable access control
-.Ve
-.PP
-Because no buf is passed to this callback, the usual buf-related keywords
-are not applicable here.
-.PP
-The information sent in the parameter list is arbitrary.  However, we
-envision sending information such as file names or \s-1XPA\s0 access points
-from which to collect more data.  Note that the xpainfo program and
-the \fIXPAInfo()\fR routine that cause the info_callback to execute do not
-wait for the callback to complete before returning.

-\&  xpa_cendian           endian\-ness of client ("little" or "big"
-.Ve
-.PP
-The argument to these macros is the call_data pointer that is passed
-to the server procedure.  This pointer should be type case to \s-1XPA\s0
-in the server routine:
-.PP
-.Vb 1
-\&  XPA xpa = (XPA)call_data;
-.Ve
-.PP
-The most important of these macros is \fIxpa_datafd()\fR.  A server routine
-that sets \*(L"fillbuf=false\*(R" in receive_mode or send_mode can use this
-macro to perform I/O directly to/from the client, rather than using
-buf.
-.PP
-The xpa_cendian and xpa_sendian macros can be used together to determine
-if the data transferred from the client is byte swapped with respect
-to the server. Values for these macros are: \*(L"little\*(R", \*(L"big\*(R", or \*(L"?\*(R".
-In order to do a proper conversion, you still need to know the format
-of the data (i.e., byte swapping is dependent on the size of the data
-element being converted).

-.SH "DESCRIPTION"
-.IX Header "DESCRIPTION"
-Once \s-1XPA\s0 access points have been defined, a program must enter an
-event loop to watch for requests from external programs. This can be
-done in a variety of ways, depending on whether the event loop is
-processing events other than \s-1XPA\s0 events.  In cases where there are no
-non-XPA events to be processed, the program can simply call the
-\&\fIXPAMainLoop()\fR event loop.  This loop is implemented essentially as
-follows (error checking is simplified in this example):
-.PP
-.Vb 8
-\&  FD_ZERO(&readfds);
-\&  while( XPAAddSelect(NULL, &readfds) ){
-\&    if( sgot = select(swidth, &readfds, NULL, NULL, NULL) >0 )
-\&      XPAProcessSelect(&readfds, 0);
-\&    else
-\&      break;
-\&    FD_ZERO(&readfds);
-\&  }
-.Ve
-.PP
-The \fIXPAAddSelect()\fR routine sets up the \fIselect()\fR readfds variable so
-that \fIselect()\fR will wait for I/O on all the active \s-1XPA\s0 channels.  It
-returns the number of XPAs that are active; the loop will end when
-there are no active XPAs. The standard \fIselect()\fR routine is called to
-wait for an external I/O request.  Since no timeout struct is passed
-in argument 5, the \fIselect()\fR call hangs until there is an external
-request.  When an external I/O request is made, the \fIXPAProcessSelect()\fR
-routine is executed to process the pending requests.  In this routine,
-the maxreq value determines how many requests will be processed: if
-maxreq <=0, then all currently pending requests will be processed.
-Otherwise, up to maxreq requests will be processed.  (The most usual
-values for maxreq is 0 to process all requests.)
-.PP
-If a program has its own Unix \fIselect()\fR loop, then \s-1XPA\s0 access points can
-be added to it by using a variation of the standard XPAMainLoop:
-.PP
-.Vb 7
-\&  XPAAddSelect(xpa, &readfds);
-\&  [app\-specific ...]
-\&  if( select(width, &readfds, ...) ){
-\&    XPAProcessSelect(&readfds, maxreq);
-\&    [app\-specific ...]
-\&    FD_ZERO(&readfds);
-\&  }
-.Ve
-.PP
-\&\fIXPAAddSelect()\fR is called before \fIselect()\fR to add the access points.
-If the first argument is \s-1NULL\s0, then all active \s-1XPA\s0 access points
-are added. Otherwise only the specified access point is added.
-After \fIselect()\fR is called, the \fIXPAProcessSelect()\fR routine can be called
-to process \s-1XPA\s0 requests.  Once again, the maxreq value determines how
-many requests will be processed: if maxreq <=0, then all currently
-pending requests will be processed.  Otherwise, up to maxreq requests
-will be processed.
-.PP
-\&\s-1XPA\s0 access points can be added to
-Xt event loops (using \fIXtAppMainLoop()\fR)
-and
-Tcl/Tk event loops (using vwait and the Tk loop).
-When using \s-1XPA\s0 with these event loops, you only need to call:
-.PP
-int XPAXtAddInput(XtAppContext app, \s-1XPA\s0 xpa)
-.PP
-or
-.PP
-.Vb 1
-\&  int XPATclAddInput(XPA xpa)
-.Ve
-.PP
-respectively before entering the loop.

-Create a new \s-1XPA\s0 public access point with the class:name
-identifier template
-and enter this access point into the \s-1XPA\s0 name server, so that it
-can be accessed by external processes. \fIXPANew()\fR returns an \s-1XPA\s0 struct.
-Note that the length of the class and name designations must be less
-than or equal to 1024 characters each.
-.PP
-The \s-1XPA\s0 name server daemon, xpans, will be started automatically if it
-is not running already (assuming it can be found in the path).  The
-program's ip address and listening port are specified by the
-environment variable \s-1XPA_NSINET\s0, which takes the form :.  If
-no such environment variable exists, then xpans is started on the
-current machine listening on port 14285.  It also uses 14286 as a
-known port for its public access point (so that routines do not have
-to go to the name server to find the name server ip and port!)
-As of \s-1XPA\s0 2.1.1, version information is exchanged between the xpans
-process and the new access point. If the access point uses an \s-1XPA\s0
-major/minor version newer than xpans, a warning is issued by both processes,
-since mixing of new servers and old xpa programs (xpaset, xpaget,
-xpans, etc.) is not likely to work. You can turn off the warning
-message by setting the \s-1XPA_VERSIONCHECK\s0 environment variable to \*(L"false\*(R".
-.PP
-The help string is meant to be returned by a request from xpaget:
-.PP
-.Vb 1
-\&  xpaget class:name \-help
-.Ve
-.PP
-A send_callback and/or a receive_callback can be specified; at
-least one of them must be specified.
-.PP
-A send_callback can be specified that will be executed in response to
-an external request from the xpaget program, the \fIXPAGet()\fR routine, or
-\&\fIXPAGetFd()\fR routine. This callback is used to send data to the
-requesting client.
-.PP
-The calling sequence for \fIsend_callback()\fR is:
-.PP
-.Vb 7
-\&  int send_callback(void *send_data, void *call_data,
-\&    char *paramlist, char **buf, size_t *len)
-\&  {
-\&    XPA xpa = (XPA)call_data;
-\&    ...
-\&    return(stat);
-\&  }
-.Ve
-.PP
-The send_mode string is of the form: \*(L"key1=value1,key2=value2,...\*(R"
-The following keywords are recognized:
-.PP
-.Vb 4
-\&  key           value           default         explanation
-\&  \-\-\-\-\-\-        \-\-\-\-\-\-\-\-        \-\-\-\-\-\-\-\-        \-\-\-\-\-\-\-\-\-\-\-
-\&  acl           true/false      true            enable access control
-\&  freebuf       true/false      true            free buf after callback completes
-.Ve
-.PP
-The call_data should be recast to the \s-1XPA\s0 struct as shown.  In
-addition, client-specific data can be passed to the callback in
-send_data.
-.PP
-The paramlist will be supplied by the client as qualifying parameters
-for the callback.  There are two ways in which the \fIsend_callback()\fR
-routine can send data back to the client:
-.PP
-1. The \fIsend_callback()\fR routine can fill in a buffer and pass back a
-pointer to this buffer. An integer len also is returned to specify the
-number of bytes of data in buf.  \s-1XPA\s0 will send this buffer to the
-client after the callback is complete.
-.PP
-2. The send_callback can send data directly to the client by writing
-to the fd pointed by the macro:
-.PP
-.Vb 1
-\&  xpa_datafd(xpa)
-.Ve
-.PP
-Note that this fd is of the kind returned by \fIsocket()\fR or \fIopen()\fR.
-.PP
-If a buf has been allocated by a standard malloc routine, filled, and
-returned to \s-1XPA\s0, then freebuf generally is set so that the buffer will
-be freed automatically when the callback is completed and data has
-been sent to the client.  If a static buf is returned, freebuf should
-be set to false to avoid a system error when freeing static storage.
-Note that default value for freebuf implies that the callback will
-allocate a buffer rather than use static storage.
-.PP
-On the other hand, if buf is dynamically allocated using a method
-other than a standard malloc/calloc/realloc routine (e.g. using Perl's
-memory allocation and garbage collection scheme), then it is necessary
-to tell \s-1XPA\s0 how to free the allocated buffer. To do this, use the
-\&\fIXPASetFree()\fR routine within your callback:
-.PP
-.Vb 1
-\&  void XPASetFree(XPA xpa, void (*myfree)(void *), void *myfree_ptr);
-.Ve
-.PP
-The first argument is the usual \s-1XPA\s0 handle. The second argument is the
-special routine to call to free your allocated memory. The third
-argument is an optional pointer.  If not \s-1NULL\s0, the specified free
-routine is called with that pointer as its sole argument. If \s-1NULL\s0, the
-free routine is called with the standard buf pointer as its sole
-argument. This is useful in cases where there is a mapping between the
-buffer pointer and the actual allocated memory location, and the
-special routine is expecting to be passed the former.
-.PP
-If, while the callback performs its processing, an error occurs that
-should be communicated to the client, then the routine XPAError should be
-called:
-.PP
-.Vb 1
-\&  XPAError(XPA xpa, char *s);
-.Ve
-.PP
-where s is an arbitrary error message.  The returned error message
-string will be of the form:
-.PP
-.Vb 1
-\&  XPA$ERROR   [error] (class:name ip:port)
-.Ve
-.PP
-If the callback wants to send a specific acknowledgment message back
-to the client, the routine XPAMessage can be called:
-.PP
-.Vb 1
-\&  XPAMessage(XPA xpa, char *s);
-.Ve
-.PP
-where s is an arbitrary error message.  The returned error message
-string will be of the form:
-.PP
-.Vb 1
-\&  XPA$MESSAGE [message] (class:name ip:port)
-.Ve
-.PP
-Otherwise, a standard acknowledgment is sent back to the client
-after the callback is completed.
-.PP
-The callback routine should return 0 if no error occurs, or \-1 to
-signal an error.
-.PP
-A receive_callback can be specified that will be executed in response
-to an external request from the xpaset program, or the XPASet (or
-\&\fIXPASetFd()\fR) routine. This callback is used to process data received
-from an external process.
-.PP
-The calling sequence for receive_callback is:
-.PP
-.Vb 7
-\&  int receive_callback(void *receive_data, void *call_data,
-\&    char *paramlist, char *buf, size_t len)
-\&  {
-\&    XPA xpa = (XPA)call_data;
-\&    ...
-\&    return(stat);
-\&  }
-.Ve
-.PP
-The mode string is of the form: \*(L"key1=value1,key2=value2,...\*(R"
-The following keywords are recognized:
-.PP
-.Vb 6
-\&  key           value           default         explanation
-\&  \-\-\-\-\-\-        \-\-\-\-\-\-\-\-        \-\-\-\-\-\-\-\-        \-\-\-\-\-\-\-\-\-\-\-
-\&  acl           true/false      true            enable access control
-\&  buf           true/false      true            server expects data bytes from client
-\&  fillbuf       true/false      true            read data into buf before executing callback
-\&  freebuf       true/false      true            free buf after callback completes
-.Ve
-.PP
-The call_data should be recast to the \s-1XPA\s0 struct as shown.  In
-addition, client-specific data can be passed to the callback in
-receive_data.
-.PP
-The paramlist will be supplied by the client. In addition, if the
-receive_mode keywords buf and fillbuf are true, then on entry into the
-\&\fIreceive_callback()\fR routine, buf will contain the data sent by the
-client. If buf is true but fillbuf is false, it becomes the callback's
-responsibility to retrieve the data from the client, using the data fd
-pointed to by the macro xpa_datafd(xpa).  If freebuf is true, then buf
-will be freed when the callback is complete.
-.PP
-If, while the callback is performing its processing, an error occurs
-that should be communicated to the client, then the routine XPAError
-can be called:
-.PP
-.Vb 1
-\&  XPAError(XPA xpa, char *s);
-.Ve
-.PP
-where s is an arbitrary error message.
-.PP
-The callback routine should return 0 if no error occurs, or \-1 to

-.SH "NAME"
-\&\fBXPANSLookup: lookup registered \s-1XPA\s0 access points\fR
-.SH "SYNOPSIS"
-.IX Header "SYNOPSIS"
-.Vb 1
-\&  #include <xpa.h>
-\&
-\&  int XPANSLookup(XPA xpa,
-\&                  char *template, char type,
-\&                  char ***classes, char ***names,
-\&                  char ***methods, char ***infos)
-.Ve
-.SH "DESCRIPTION"
-.IX Header "DESCRIPTION"
-\&\s-1XPA\s0 routines act on a class:name identifier in such a way
-that all access points that match the identifier are processed.  It is
-sometimes desirable to choose specific access points from the
-candidates that match the
-template.  In order to do this, the
-XPANSLookup routine can be called to return a list of matches, so that
-specific class:name instances can then be fed to \fIXPAGet()\fR, \fIXPASet()\fR, etc.
-.PP
-.Vb 4
-\& The first argument is an optional XPA struct. If non\-NULL, the
-\&existing name server connection associated with the specified xpa is
-\&used to query the xpans name server for matching templates. Otherwise,
-\&a new (temporary) connection is established with the name server.
-.Ve
-.PP
-The second argument to XPANSLookup is the class:name 
-template
-to match.
-.PP
-The third argument for \fIXPANSLookup()\fR is the type of access and can be
-any combination of:
-.PP
-.Vb 5
-\&  type          explanation
-\&  \-\-\-\-\-\-        \-\-\-\-\-\-\-\-\-\-\-
-\&  g             xpaget calls can be made on this access point
-\&  s             xpaset calls can be made on this access point
-\&  i             xpainfo calls can be made on this access point
-.Ve
-.PP
-The call typically specifies only one of these at a time.
-.PP
-The final arguments are pointers to arrays that will be filled
-in and returned by the name server. The name server will allocate and
-return arrays filled with the classes, names, and methods of all \s-1XPA\s0
-access points that match the template
-and have the specified type. Also returned are info strings, which
-generally are used internally by the client routines. These can be
-ignored (but the strings must be freed).  The function returns the
-number of matches. The returned value can be used to loop through the
-matches:
-.PP
-\&\fBExample:\fR
-.PP
-.Vb 1
-\&  #include <xpa.h>
-\&
-\&  char **classes;
-\&  char **names;
-\&  char **methods;
-\&  char **infos;
-\&  int i, n;
-\&  n = XPANSLookup(NULL, "foo*", "g", &classes, &names, &methods, &infos);
-\&  for(i=0; i<n; i++){
-\&    [more specific checks on possibilities ...]
-\&    [perhaps a call to XPAGet for those that pass, etc. ...]
-\&    /* don\*(Aqt forget to free alloc\*(Aqed strings when done */
-\&    free(classes[i]);
-\&    free(names[i]);
-\&    free(methods[i]);
-\&    free(infos[i]);
-\&  }
-\&  /* free up arrays alloc\*(Aqed by names server */
-\&  if( n > 0 ){
-\&    free(classes);
-\&    free(names);
-\&    free(methods);
-\&    free(infos);
-\&  }
-.Ve
-.PP
-The specified 
-template
-also can be a host:port specification, for example:
-.PP
-.Vb 1
-\&  myhost:12345
-.Ve
-.PP
-In this case, no connection is made to the name server. Instead, the
-call will return one entry such that the ip array contains the ip for
-the specified host and the port array contains the port.  The class
-and name entries are set to the character \*(L"?\*(R", since the class and
-name of the access point are not known.

-.PP
-.Vb 1
-\&  XPAPoll(int msec, int maxreq);
-.Ve
-.PP
-The \fIXPAPoll()\fR routine will perform \fIXPAAddSelect()\fR and \fIselect()\fR, but with a
-timeout specified in millisecs by the msec argument. If one or more
-\&\s-1XPA\s0 requests are made before the timeout expires, the \fIXPAProcessSelect()\fR
-routine is called to process those requests. The maxreq value determines
-how many requests will be processed: if maxreq < 0, then no events are
-processed, but instead, the return value indicates the number of events
-that are pending.  If maxreq == 0, then all currently pending requests
-will be processed.  Otherwise, up to maxreq requests will be processed.
-(The most usual values for maxreq are 0 to process all requests and 1
-to process one request).

-\&\fB\s-1XPA\s0 Race Conditions\fR
-.SH "SYNOPSIS"
-.IX Header "SYNOPSIS"
-Potential \s-1XPA\s0 race conditions and how to avoid them.
-.SH "DESCRIPTION"
-.IX Header "DESCRIPTION"
-Currently, there is only one known circumstance in which \s-1XPA\s0 can get
-(temporarily) deadlocked in a race condition: if two or more \s-1XPA\s0
-servers send messages to one another using an \s-1XPA\s0 client routine such
-as \fIXPASet()\fR, they can deadlock while each waits for the other server
-to respond.  (This can happen if the servers call \fIXPAPoll()\fR with a
-time limit, and send messages in between the polling call.)  The
-reason this happens is that both client routines send a string to the
-other server to establish the handshake and then wait for the server
-response. Since each client is waiting for a response, neither is able
-to enter its event-handling loop and respond to the other's
-request. This deadlock will continue until one of the timeout periods
-expire, at which point an error condition will be triggered and the
-timed-out server will return to its event loop.
-.PP
-Starting with version 2.1.6, this rare race condition can be
-avoided by setting the \s-1XPA_IOCALLSXPA\s0 environment variable for servers
-that will make client calls. 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. It also means that a server callback
-routine can handle incoming \s-1XPA\s0 messages if it makes its own \s-1XPA\s0 call.
-The semi-public routine oldvalue=XPAIOCallsXPA(newvalue) can be used
-to turn this behavior off and on temporarily. Passing a 0 will turn
-off \s-1IO\s0 processing, 1 will turn it back on. The old value is returned
-by the call.
-.PP
-By default, the \s-1XPA_IOCALLSXPA\s0 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.
-.PP
-Aside from setting \s-1XPA_IOCALLSXPA\s0, the simplest way to avoid this race
-condition is to multi-process: when you want to send a client message,
-simply start a separate process to call the client routine, so that
-the server is not stopped. It probably is fastest and easiest to use
-\&\fIfork()\fR and then have the child call the client routine and exit. But
-you also can use either the \fIsystem()\fR or \fIpopen()\fR routine to start one
-of the command line programs and do the same thing. Alternatively, you
-can use \s-1XPA\s0's internal \fIlaunch()\fR routine instead of \fIsystem()\fR. Based on
-\&\fIfork()\fR and \fIexec()\fR, this routine is more secure than \fIsystem()\fR because
-it does not call /bin/sh.
-.PP
-Starting with version 2.1.5, you also can send an \fIXPAInfo()\fR message with
-the mode string \*(L"ack=false\*(R". This will cause the client to send a message
-to the server and then exit without waiting for any return message from
-the server. This UDP-like behavior will avoid the server deadlock when
-sending short XPAInfo messages.

-\&\fBIntroduction\fR
-.PP
-To use the \s-1XPA\s0 application programming interface, a software developer
-generally will include the xpa.h definitions file:
-.PP
-.Vb 1
-\&  #include <xpa.h>
-.Ve
-.PP
-in the software module that defines or accesses an \s-1XPA\s0 access point, and
-then will link against the libxpa.a library:
-.PP
-.Vb 1
-\&  gcc \-o foo foo.c libxpa.a
-.Ve
-.PP
-\&\s-1XPA\s0 has been compiled using both C and \*(C+ compilers.
-.PP
-A server program generally defines an \s-1XPA\s0 access point by calling the
-\&\fIXPANew()\fR routine and specifies \*(L"send\*(R" and/or \*(L"receive\*(R" callback
-procedures 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. A program also can define several
-sub-commands for a single access point by calling \fIXPACmdNew()\fR and
-\&\fIXPACmdAdd()\fR instead.  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).

-when the call completes).
-.PP
-The \fIXPASet()\fR routine transfers data from buf to the \s-1XPA\s0 servers.
-The length of buf (in bytes) should be placed in the len variable.
-.PP
-A string containing the class:name and ip:port of each of these server
-is returned in the name array.  If a given server returned an error or
-the server callback sends a message back to the client, then the
-message will be stored in the associated element of the messages
-array. \s-1NB:\s0 if specified, the name and messages arrays must be of size

-.PP
-.Vb 1

-.PP
-The return value will contain the actual number of servers that were

-Normally, an \s-1XPA\s0 client will process incoming \s-1XPA\s0 server requests
