XPAXt - the XPA Interface to Xt (X Windows)
SYNOPSIS
Describes how XPA access points can be added to X Toolkit (Xt) programs.
DESCRIPTION
XPA supports Xt programs: you can call XPANew(), XPACmdNew(), or XPAInfoNew() within any C routine to add XPA server callbacks to an Xt
program. Since an Xt program has its own event loop call (i.e., XtAppMainLoop()), it therefore does not need or want to use the XPA even
loop. Thus, in order to add XPA access points to the standard Xt event loop, the following routine should be called before entering the
loop:
int XPAXtAddInput(XtAppContext app, XPA xpa)
The XPAAddAddInput() routine will add XPA access points to the Xt event loop by making calls to the standard XtAppAddInput() routine. (If
the XtAppContext argument is NULL, then the alternate XtAddInput() routine is used instead.) If the xpa argument is NULL, then all active
XPA access points are added to the loop. If xpa is not NULL, then only the specified access point is added. The latter type of call is
used to add new access points from within a callback, after the program has entered the XtAppMainLoop() even loop.

XPACmdAdd - add a command to an XPA command public access point
SYNOPSIS
#include <xpa.h>
XPACmd XPACmdAdd(XPA xpa, char *name, char *help,
int (*send_callback)(),
void *send_data, char *send_mode,
int (*rec_callback)(),
void *rec_data, char *rec_mode);
DESCRIPTION
Add a command to an XPA command access point. The XPA argument specifies the XPA struct returned by a call to XPANewCmd(). The name argu-
ment is the name of the command. The other arguments function identically to the arguments in the XPANew() command, i.e., the send_callback
and rec_callback routines have identical calling sequences to their XPANew() counterparts, with the exceptions noted below.
When help is requested for a command access point using:
xpaget -h class:name
all of the command help strings are listed. To get help for a given command, use:
xpaget -h class:name cmd
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).
