XFlush() XFlush()
Name
XFlush - send all queued requests to the server.
Synopsis
XFlush(display)
Display *display;
Arguments
display Specifies a connection to an X server; returned from XOpenDisplay().
Description
XFlush() sends to the server ("flushes") all requests that have been buffered but not yet sent.
Flushing is done automatically when input is read if no matching events are in Xlib's queue (with XPending(), XNextEvent(), or XWindow-
Event(), etc.), or when a call is made that gets information from the server (such as XQueryPointer(), XGetFontInfo) so XFlush() is seldom
needed. It is used when the buffer must be flushed before any of these calls are reached.
For more information, see Volume One, Chapter 2, X Concepts, and Chapter 3, Basic Window Program.
