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. +.PP +Choose from the following topics: +.IP "\(bu" 4 +Introduction to \s-1XPA\s0 +[xpaintro(n)] +.IP "\(bu" 4 +Access Point Names and Templates +[xpatemplate(n)] +.IP "\(bu" 4 +Getting Common Information About Access Points +[xpacommon(n)] +.IP "\(bu" 4 +Communication Methods +[xpamethod(n)] +.IP "\(bu" 4 +Communication Between Hosts +[xpainet(n)] +.IP "\(bu" 4 +Distinguishing Users +[xpausers(n)] +.IP "\(bu" 4 +\&\s-1XPA\s0 User Programs +.RS 4 +.IP "\(bu" 4 +xpaget: get data and info +[\fIxpaget\fR\|(1)] +.IP "\(bu" 4 +xpaset: send data and info +[\fIxpaset\fR\|(1)] +.IP "\(bu" 4 +xpainfo: send info alert +[\fIxpainfo\fR\|(1)] +.IP "\(bu" 4 +xpaaccess: get access point info +[\fIxpaaccess\fR\|(1)] +.IP "\(bu" 4 +xpamb: message bus emulation +[\fIxpamb\fR\|(1)] +.IP "\(bu" 4 +xpans: the \s-1XPA\s0 name server +[\fIxpans\fR\|(1)] +.RE +.RS 4 +.RE +.IP "\(bu" 4 +\&\s-1XPA\s0 Server Routines +.RS 4 +.IP "\(bu" 4 +XPANew: define a new access point +[\fIxpanew\fR\|(3)] +.IP "\(bu" 4 +XPACmdNew: define a new command access point +[\fIxpacmdnew\fR\|(3)] +.IP "\(bu" 4 +XPACmdAdd: add a command +[\fIxpacmdadd\fR\|(3)] +.IP "\(bu" 4 +XPACmdDel: delete a command +[\fIxpacmddel\fR\|(3)] +.IP "\(bu" 4 +XPAInfoNew: define an info access point +[\fIxpainfonew\fR\|(3)] +.IP "\(bu" 4 +XPAFree: free an access point +[\fIxpafree\fR\|(3)] +.IP "\(bu" 4 +XPAMainLoop: event loop for select server +[\fIxpamainloop\fR\|(3)] +.IP "\(bu" 4 +XPAPoll: poll for \s-1XPA\s0 events +[\fIxpapoll\fR\|(3)] +.IP "\(bu" 4 +XPACleanup: release reserved \s-1XPA\s0 memory +[\fIxpacleanup\fR\|(3)] +.IP "\(bu" 4 +\&\s-1XPA\s0 Server Macros: accessing structure internals +[\fIxpamacros\fR\|(3)] +.IP "\(bu" 4 +\&\s-1XPA\s0 Race Conditions: how to avoid them +[\fIxparace\fR\|(3)] +.IP "\(bu" 4 +\&\s-1XPA\s0 Out of Memory (\s-1OOM\s0) errors +[\fIxpaoom\fR\|(3)] +.RE +.RS 4 +.RE +.IP "\(bu" 4 +\&\s-1XPA\s0 Client Routines +.RS 4 +.IP "\(bu" 4 +XPAOpen: open a persistent client connection +[\fIxpaopen\fR\|(3)] +.IP "\(bu" 4 +XPAClose: close persistent client connection +[\fIxpaclose\fR\|(3)] +.IP "\(bu" 4 +XPAGet: get data +[\fIxpaget\fR\|(3)] +.IP "\(bu" 4 +XPASet: send data or commands +[\fIxpaset\fR\|(3)] +.IP "\(bu" 4 +XPAInfo: send an info alert +[\fIxpainfo\fR\|(3)] +.IP "\(bu" 4 +XPAGetFd: get data and write to an fd +[\fIxpagetfd\fR\|(3)] +.IP "\(bu" 4 +XPASetFd: read data from and fd and send +[\fIxpasetfd\fR\|(3)] +.IP "\(bu" 4 +XPANSLookup: look up an access point +[\fIxpanslookup\fR\|(3)] +.IP "\(bu" 4 +XPAAccess: get access info +[\fIxpaaccess\fR\|(3)] +.IP "\(bu" 4 +The XPA/Xt Interface: Xt interface to \s-1XPA\s0 +[xpaxt(n)] +.IP "\(bu" 4 +The XPA/Tcl Interface: Tcl interface to \s-1XPA\s0 +[xpatcl(n)] +.RE +.RS 4 +.RE +.IP "\(bu" 4 +Tailoring the \s-1XPA\s0 Environment +.RS 4 +.IP "\(bu" 4 +Environment Variables +[xpaenv(n)] +.IP "\(bu" 4 +Access Control +[xpaacl(n)] +.RE +.RS 4 +.RE +.IP "\(bu" 4 +Miscellaneous +.RS 4 +.IP "\(bu" 4 +Where to Find Example/Test Code +.IP "\(bu" 4 +User Changes Between \s-1XPA\s0 1.0 and 2.0 +.IP "\(bu" 4 +\&\s-1API\s0 Changes Between \s-1XPA\s0 1.0 and 2.0 +.IP "\(bu" 4 +What Does \s-1XPA\s0 Stand For, Anyway? +.RE +.RS 4 +.RE |
