XMaskEvent() XMaskEvent()
Name
XMaskEvent - remove the next event that matches mask.
Synopsis
XMaskEvent(display, event_mask, event_return)
Display *display;
long event_mask;
XEvent *event_return;
Arguments
display Specifies a connection to an X server; returned from XOpenDisplay().
event_mask
Specifies the event mask. See XSelectInput() for a complete list of the event mask symbols that can be ORed together.
event_return
Returns the event removed from the event queue.
Description
XMaskEvent() removes the next event in the queue which matches the passed mask. The event is copied into an XEvent supplied by the caller.
Other events in the queue are not discarded. If no such event has been queued, XMaskEvent() flushes the request buffer and waits until one
is received. Use XCheckMaskEvent() if you do not wish to wait.
XMaskEvent() cannot return ClientMessage, MappingNotify, SelectionClear, SelectionNotify, or SelectionRequest events because these event
types are by definition unmaskable.
