It +also provides an easy way for users to communicate with XPA-enabled +programs by executing XPA client commands in the shell or by utilizing +such commands in scripts. Because XPA 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 XPA services, and +client access can be extended or modified easily at any time. + +<P> +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 TCP sockets as a +transport mechanism, XPA 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 XPA servers +across a network. + +<P> +XPA implements a layered interface that is designed to be useful both +to software developers and to users. The interface consists of a +library of XPA 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 XPA library, access points can be added to Tcl/Tk programs, +Xt programs, or to Unix programs that use the XPA event loop or any +event loop based on select(). 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. + +<P> +Choose from the following topics: + +<UL> +<LI><A HREF="./intro.html">Introduction to XPA</A> +<!-- =text [xpaintro(n)] --> +<LI><A HREF="./template.html">Access Point Names and Templates</A> +<!-- =text [xpatemplate(n)] --> +<LI><A HREF="./info.html">Getting Common Information About Access Points</A> +<!-- =text [xpacommon(n)] --> +<LI><A HREF="./method.html">Communication Methods</A> +<!-- =text [xpamethod(n)] --> +<LI><A HREF="./inet.html">Communication Between Hosts</A> +<!-- =text [xpainet(n)] --> +<LI><A HREF="./users.html">Distinguishing Users</A> +<!-- =text [xpausers(n)] --> + +<LI><A HREF="./programs.html">XPA User Programs</A> +<UL> +<LI><A HREF="./programs.html#xpaget">xpaget: get data and info</A> +<!-- =text [xpaget(1)] --> +<LI><A HREF="./programs.html#xpaset">xpaset: send data and info</A> +<!-- =text [xpaset(1)] --> +<LI><A HREF="./programs.html#xpainfo">xpainfo: send info alert</A> +<!-- =text [xpainfo(1)] --> +<LI><A HREF="./programs.html#xpaaccess">xpaaccess: get access point info</A> +<!-- =text [xpaaccess(1)] --> +<LI><A HREF="./xpamb.html">xpamb: message bus emulation</A> +<!-- =text [xpamb(1)] --> +<LI><A HREF="./xpans.html">xpans: the XPA name server</A> +<!-- =text [xpans(1)] --> +</UL> + +<LI><A HREF="./server.html">XPA Server Routines</A> +<UL> +<LI><A HREF="./server.html#xpanew">XPANew: define a new access point</A> +<!-- =text [xpanew(3)] --> +<LI><A HREF="./server.html#xpacmdnew">XPACmdNew: define a new command access point</A> +<!-- =text [xpacmdnew(3)] --> +<LI><A HREF="./server.html#xpacmdadd">XPACmdAdd: add a command</A> +<!-- =text [xpacmdadd(3)] --> +<LI><A HREF="./server.html#xpacmddel">XPACmdDel: delete a command</A> +<!-- =text [xpacmddel(3)] --> +<LI><A HREF="./server.html#xpainfonew">XPAInfoNew: define an info access point</A> +<!-- =text [xpainfonew(3)] --> +<LI><A HREF="./server.html#xpafree">XPAFree: free an access point</A> +<!-- =text [xpafree(3)] --> +<LI><A HREF="./server.html#xpamainloop">XPAMainLoop: event loop for select server</A> +<!-- =text [xpamainloop(3)] --> +<LI><A HREF="./server.html#xpapoll">XPAPoll: poll for XPA events</A> +<!-- =text [xpapoll(3)] --> +<LI><A HREF="./server.html#xpacleanup">XPACleanup: release reserved XPA memory</A> +<!-- =text [xpacleanup(3)] --> +<LI><A HREF="./server.html#macros">XPA Server Macros: accessing structure internals</A> +<!-- =text [xpamacros(3)] --> +<LI><A HREF="./server.html#race">XPA Race Conditions: how to avoid them</A> +<!-- =text [xparace(3)] --> +<LI><A HREF="./oom.html">XPA Out of Memory (OOM) errors</A> +<!-- =text [xpaoom(3)] --> +</UL> + +<LI><A HREF="./client.html">XPA Client Routines</A> +<UL> +<LI><A HREF="./client.html#xpaopen">XPAOpen: open a persistent client connection</A> +<!-- =text [xpaopen(3)] --> +<LI><A HREF="./client.html#xpaclose">XPAClose: close persistent client connection</A> +<!-- =text [xpaclose(3)] --> +<LI><A HREF="./client.html#xpaget">XPAGet: get data</A> +<!-- =text [xpaget(3)] --> +<LI><A HREF="./client.html#xpaset">XPASet: send data or commands</A> +<!-- =text [xpaset(3)] --> +<LI><A HREF="./client.html#xpainfo">XPAInfo: send an info alert</A> +<!-- =text [xpainfo(3)] --> +<LI><A HREF="./client.html#xpagetfd">XPAGetFd: get data and write to an fd</A> +<!-- =text [xpagetfd(3)] --> +<LI><A HREF="./client.html#xpasetfd">XPASetFd: read data from and fd and send</A> +<!-- =text [xpasetfd(3)] --> +<LI><A HREF="./client.html#xpanslookup">XPANSLookup: look up an access point</A> +<!-- =text [xpanslookup(3)] --> +<LI><A HREF="./client.html#xpaaccess">XPAAccess: get access info</A> +<!-- =text [xpaaccess(3)] --> +<LI><A HREF="./xt.html">The XPA/Xt Interface: Xt interface to XPA</A> +<!-- =text [xpaxt(n)] --> +<LI><A HREF="./tcl.html">The XPA/Tcl Interface: Tcl interface to XPA</A> +<!-- =text [xpatcl(n)] --> +</UL> + +<LI> Tailoring the XPA Environment +<UL> +<LI><A HREF="./env.html">Environment Variables</A> +<!-- =text [xpaenv(n)] --> +<LI><A HREF="./acl.html">Access Control</A> +<!-- =text [xpaacl(n)] --> +</UL> + +<LI> Miscellaneous +<UL> +<!-- =stop --> +<LI><A HREF="./changelog.html">XPA ChangeLog</A> +<!-- =cont --> +<LI><A HREF="./examples.html">Where to Find Example/Test Code</A> +<LI><A HREF="./changes.html">User Changes Between XPA 1.0 and 2.0</A> +<LI><A HREF="./convert.html">API Changes Between XPA 1.0 and 2.0</A> +<LI><A HREF="./name.html">What Does XPA Stand For, Anyway?</A> +</UL> + +</UL> + +<!-- =stop --> + +<H5>Last updated: September 10, 2003</H5> +</BODY> +</HTML> |
