Name
XPending – return the number of pending events.
Synopsis
int XPending(display)
Display *display;
Arguments
display Specifies a connection to an X server; returned from
XOpenDisplay().
Returns
The number of events.
Description
XPending() returns the number of events that have been received by Xlib
from the server, but not yet removed from the queue. If there are no
events on the queue, XPending() flushes the request buffer, and returns
the number of events transferred to the input queue as a result of the
flush.
The QLength macro or XQLength() returns the number of events on the
queue, but without flushing the request buffer first.
For more information, see Volume One, Chapter 8, Events.
