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. - -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. - -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. - -To build XPA, see the INSTALL instructions (which are based on -standard instructions for building software using GNU configure). - -Documentation for XPA is contained in the doc subdirectory (where the -help.html file is the top-level index). - -If you have questions, please contact us at: saord@cfa.harvard.edu. - - Eric Mandel - -XPA is distributed under the terms of The MIT License. |
