XtAddExposureToRegion(3)	 XT FUNCTIONS	      XtAddExposureToRegion(3)

NAME
       XtAddExposureToRegion - merge exposure events into a region

SYNTAX
       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
       Expose 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).
