MirOS Manual: XCreateRegion(3), XDestroyRegion(3), XSetRegion(3)

XCreateRegion(3X11)      XLIB FUNCTIONS       XCreateRegion(3X11)


     XCreateRegion, XSetRegion, XDestroyRegion - create or des-
     troy regions


     Region XCreateRegion(void);

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

     int XDestroyRegion(Region r);


     display   Specifies the connection to the X server.

     gc        Specifies the GC.

     r         Specifies the region.


     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 associ-
     ated with a specified region.
