             GC gc;
             Region r;

       XDestroyRegion(r)
             Region r;

ARGUMENTS
       display   Specifies the connection to the X server.

       gc        Specifies the GC.

       r         Specifies the region.

DESCRIPTION
       The XCreateRegion function creates a new empty region.

       The XSetRegion function sets the clip-mask in the GC to
       the specified region.  The region is specified relative to
       the drawable's origin.  The resulting GC clip origin is
       implementation-dependent.  Once it is set in the GC, the
       region can be destroyed.

       The XDestroyRegion function deallocates the storage asso-
       ciated with a specified region.
