 I am trying to make a main event handler which will run for at least
the given time, and returns the control back to the program.
That is, it should be a temparary XtAppMainLoop.

 I made up the following function:

void TempEventH(XtAppContext app, unsigned int time)
{
  XEvent event;

  XtAppAddTimeOut(app, time, NULL, NULL);  /* put up a timer event */
  while(!(XtAppPending(app) & XtIMTimer)){ /* until it arrives */
    XtAppNextEvent(app, &event);           /* do the event  processing */
    XtDispatchEvent(&event);
  }
}  

 Of course, it does not work.  But, I don't know why.
Any suggestions?  Many thanks in advance.
