=head1 NAME
B<XPAAtExit: install exit handler>
=head1 SYNOPSIS
#include <xpa.h>
void XPAAtExit(void);
=head1 DESCRIPTION
XPAAtExit() will install an exit handler using atexit() to run XPAFree on all
XPA access points. This might be useful in cases where Unix sockets are being
used: if an explicit call to XPAFree() is not made by the program, the Unix
socket file will not be deleted immediately without an atexit handler. (NB: this
call should not be made in a Tcl/Tk application. Accessing the Tcl native file
system after Tcl has shut down all file systems causes the Tcl/Tl program to
crash).
