       XCreateRegion, XSetRegion, XDestroyRegion - create or destroy regions

SYNTAX

       Region XCreateRegion(void);

       int XSetRegion(Display *display, GC gc, Region r);

       int XDestroyRegion(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 associated with a specified region.
