XtAddExposureToRegion(3)	 XT FUNCTIONS	      XtAddExposureToRegion(3)

NAME
       XtAddExposureToRegion - merge exposure events into a region

SYNTAX
       #include	<X11/Intrinsic.h>

       void XtAddExposureToRegion(XEvent *event, Region	region);

ARGUMENTS
       event	 Specifies a pointer to	the Expose or GraphicsExpose event.

       region	 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 Ex-
       pose or GraphicsExpose event, XtAddExposureToRegion returns without an
       error and without modifying region.

       This function is	used by	the exposure compression mechanism (see	Sec-
       tion 7.9.3).
