XtAppGetSelectionTimeout, XtAppSetSelectionTimeout - set and obtain selection timeout values

app_context
                 Specifies the application context.

       timeout   Specifies the selection timeout in milliseconds.

       The  XtAppGetSelectionTimeout function returns the current selection timeout value, in milliseconds.  The
       selection timeout is the time within which  the  two  communicating  applications  must  respond  to  one
       another.   The  initial  timeout  value  is  set  by  the  selectionTimeout  application resource, or, if
       selectionTimeout is not specified, it defaults to five seconds.

       The XtAppSetSelectionTimeout function sets the Intrinsics's selection timeout mechanism.  Note that  most
       applications should not set the selection timeout.
