NAME

       XPAClient -  The XPA Client-side Programming Interface

SYNOPSIS

       A description of the XPA client-side programming interface.

DESCRIPTION

       Introduction to XPA Client Programming

       Sending/receiving data to/from an XPA access point is easy: you generally only need to
       call the XPAGet() or XPASet() subroutines.

         #include <xpa.h>

         int XPAGet(XPA xpa,
             char *template, char *paramlist, char *mode,
             char **bufs, size_t *lens, char **names, char **messages, int n);

         int XPASet(XPA xpa,
             char *template, char *paramlist, char *mode,
             char *buf, size_t len, char **names, char **messages, int n);

         int XPAInfo(XPA xpa,
             char *template, char *paramlist, char *mode,
             char **names, char **messages, int n);

         int XPAAccess(XPA xpa,
             char *template, char *paramlist, char *mode,
             char **names, char **messages, int n);

         int XPAGetFd(XPA xpa,
             char *template, char *paramlist, char *mode,
             int *fds, char **names, char **messages, int n);

         int XPASetFd(XPA xpa,
             char *template, char *paramlist, char *mode,
             int fd, char **names, char **messages, int n);

         XPA XPAOpen(char *mode);

         void XPAClose(XPA xpa);

         int XPANSLookup(XPA xpa,
             char *template, char *type,
             char ***classes, char ***names, char ***methods, char ***infos);

       Introduction

       To use the XPA application programming interface, a software developer generally will
       include the xpa.h definitions file:

         #include <xpa.h>

       in the software module that defines or accesses an XPA access point and then will link
       against the libxpa.a library:

         gcc -o foo foo.c libxpa.a

       XPA has been compiled using both C and C++ compilers.

       Client communication with XPA public access points generally is accomplished using
       XPAGet() or XPASet() 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., "ds9*"), then communication will take place with all
       servers matching that template.
