NAME

       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.
