NAME
XPAAtExit - install exit handler
SYNOPSIS
#include <xpa.h>
void XPAAtExit(void);
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).
