LONG GpiRectInRegion(hps, hrgn, prcl)
HPS hps;        /* presentation-space handle      */
HRGN hrgn;      /* region handle                  */
PRECTL prcl;    /* address of rectangle structure */
 
The GpiRectInRegion function checks whether any part of a rectangle lies
within the specified region. The function cannot be used if no device
context is associated with the presentation space.
