XtPending() XtPending()
Name
XtPending - determine if there are any events in an application's input queue.
Synopsis
XtInputMask XtPending()
Inputs
None.
Returns
An XtInputMask which indicates what kind of events, if any, are pending on app_context.
Availability
XtPending() has been superseded by XtAppPending().
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()).
Usage
XtPending() has been superseded by XtAppPending(), which performs the same function on a per-application context basis. XtPending() now
calls XtAppPending() passing the default application context created by XtInitialize(). Very few programs need multiple application con-
texts, and you can continue to use XtPending() if you initialize your application with XtInitialize(). We recommend, however, that you use
XtAppInitialize(), XtAppPending(), and the other XtApp*() application context specific functions.
See XtAppPending() for more information.
Programs rarely need this much control over the event dispatching mechanism. Most programs use XtAppMainLoop().
