-.SH DESCRIPTION
-The
-.ZN XNextEvent
-function copies the first event from the event queue into the specified
-.ZN XEvent
-structure and then removes it from the queue.
-If the event queue is empty,
-.ZN XNextEvent
-flushes the output buffer and blocks until an event is received.
-.LP
-The
-.ZN XPeekEvent
-function returns the first event from the event queue,
-but it does not remove the event from the queue.
-If the queue is empty,
-.ZN XPeekEvent
-flushes the output buffer and blocks until an event is received.
-It then copies the event into the client-supplied
-.ZN XEvent
-structure without removing it from the event queue.
-.LP
-The
-.ZN XWindowEvent
-function searches the event queue for an event that matches both the specified
-window and event mask.
-When it finds a match,
-.ZN XWindowEvent
-removes that event from the queue and copies it into the specified
-.ZN XEvent
-structure.
-The other events stored in the queue are not discarded.
-If a matching event is not in the queue,
-.ZN XWindowEvent
-flushes the output buffer and blocks until one is received.
-.LP
-The
-.ZN XCheckWindowEvent
-function searches the event queue and then the events available
-on the server connection for the first event that matches the specified window
-and event mask.
-If it finds a match,
-.ZN XCheckWindowEvent
-removes that event, copies it into the specified
-.ZN XEvent
-structure, and returns
-.ZN True .
-The other events stored in the queue are not discarded.
-If the event you requested is not available,
-.ZN XCheckWindowEvent
-returns
-.ZN False ,
-and the output buffer will have been flushed.
-.LP
-The
-.ZN XMaskEvent
-function searches the event queue for the events associated with the
-specified mask.
-When it finds a match,
-.ZN XMaskEvent
-removes that event and copies it into the specified
-.ZN XEvent
-structure.
-The other events stored in the queue are not discarded.
-If the event you requested is not in the queue,
-.ZN XMaskEvent
-flushes the output buffer and blocks until one is received.
-.LP
-The
-.ZN XCheckMaskEvent
-function searches the event queue and then any events available on the
-server connection for the first event that matches the specified mask.
-If it finds a match,
-.ZN XCheckMaskEvent
-removes that event, copies it into the specified
-.ZN XEvent
-structure, and returns
-.ZN True .
-The other events stored in the queue are not discarded.
-If the event you requested is not available,
-.ZN XCheckMaskEvent
-returns
-.ZN False ,
-and the output buffer will have been flushed.
-.LP
-The
-.ZN XCheckTypedEvent
-function searches the event queue and then any events available
-on the server connection for the first event that matches the specified type.
-If it finds a match,
-.ZN XCheckTypedEvent
-removes that event, copies it into the specified
-.ZN XEvent
-structure, and returns
-.ZN True .
-The other events in the queue are not discarded.
-If the event is not available,
-.ZN XCheckTypedEvent
-returns
-.ZN False ,
-and the output buffer will have been flushed.
-.LP
-The
-.ZN XCheckTypedWindowEvent
-function searches the event queue and then any events available
-on the server connection for the first event that matches the specified
-type and window.
-If it finds a match,
-.ZN XCheckTypedWindowEvent
-removes the event from the queue, copies it into the specified
-.ZN XEvent
-structure, and returns
-.ZN True .
-The other events in the queue are not discarded.
-If the event is not available,
-.ZN XCheckTypedWindowEvent
-returns
-.ZN False ,
-and the output buffer will have been flushed.
