.SH "NAME"
\&\fBXPAXt: the \s-1XPA\s0 Interface to Xt (X Windows)\fR
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
Describes how \s-1XPA\s0 access points can be added to X Toolkit (Xt) programs.
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\s-1XPA\s0 supports Xt programs: you can call \fIXPANew()\fR, \fIXPACmdNew()\fR, or
\&\fIXPAInfoNew()\fR within any C routine to add \s-1XPA\s0 server callbacks to an Xt
program.  Since an Xt program has its own event loop call (i.e.,
\&\fIXtAppMainLoop()\fR), it therefore does not need or want to use the \s-1XPA\s0
even loop.  Thus, in order to add \s-1XPA\s0 access points to the standard Xt
event loop, the following routine should be called before entering the
loop:
.PP
.Vb 1
\&  int XPAXtAddInput(XtAppContext app, XPA xpa)
.Ve
.PP
The \fIXPAAddAddInput()\fR routine will add \s-1XPA\s0 access points to the Xt event
loop by making calls to the standard \fIXtAppAddInput()\fR routine. (If the
XtAppContext argument is \s-1NULL\s0, then the alternate \fIXtAddInput()\fR routine
is used instead.)  If the xpa argument is \s-1NULL\s0, then all active \s-1XPA\s0
access points are added to the loop.  If xpa is not \s-1NULL\s0, 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 \fIXtAppMainLoop()\fR even loop.
