XtAppPending()							XtAppPending()

Name
  XtAppPending	-  determine  whether  any events are in an application's
  input queue.

Synopsis
  XtInputMask XtAppPending(app_context)
	 XtAppContext app_context;

Inputs
  app_context
	    Specifies the application context.

Returns
  An XtInputMask which indicates what kind of events, if any, are pending
  on app_context.

Description
  XtAppPending() returns a nonzero value if there are pending events from
  the X server, timer, or other input sources.

  The return value is a bit mask that is  the  OR  of  XtIMXEvent  (an	X
  event), XtIMTimer (a timer event-see XtAppAddTimeOut()), and XtIMAlter‐
  nateInput (an alternate input event-see XtAppAddInput()).  As a  conve‐
  nience,  the	symbolic name XtIMAll is defined as the bitwise inclusive
  OR of all event  types.   If	no  events  are	 pending,  XtAppPending()
  flushes  the	output buffers of each display in the application context
  and returns zero.  This call is the Intrinsics equivalent to	the  Xlib
  call XPending().

  XtAppPending() never blocks.

Usage
  Programs rarely need this much control over the event dispatching mech‐
  anism.  Most programs use XtAppMainLoop().

Structures
  The XtInputMask type and its possible values are defined as follows:

     typedef unsigned long    XtInputMask;

     #define XtIMXEvent		     1
     #define XtIMTimer		     2
     #define XtIMAlternateInput	     4
     #define XtIMAll (XtIMXEvent   XtIMTimer   XtIMAlternateInput)

  tEvent(1), XtAppPeekEvent(1), XtAppProcessEvent(1), XtDispatchEvent(1).
