XtAddExposureToRegion __libmansuffix__ __xorgversion__ "XT FUNCTIONS"
NAME
XtAddExposureToRegion - merge exposure events into a region
SYNTAX
#include <X11/Intrinsic.h>
void XtAddExposureToRegion(XEvent *event, Region region);
ARGUMENTS
event 1i
Specifies a pointer to the
Expose or
GraphicsExpose event.
region 1i
Specifies the region object (as defined in
<X11/Xutil.h> ). DESCRIPTION
The
XtAddExposureToRegion function computes the union of the rectangle defined by the exposure
event and the specified region.
Then, it stores the results back in region.
If the event argument is not an
Expose or
GraphicsExpose event,
XtAddExposureToRegion returns without an error and without modifying region.
This function is used by the exposure compression mechanism (see Section 7.9.3).
