This function is simulated by a handling routine in the graphics engine.

Description

GreSelectPathRegion merges a region representing a path into the DC region. A "path region" behaves exactly like any other region. It has no special properties relating to paths.

This function can be hooked by the presentation driver.

#define INCL_GRE_CLIP

HDC      hdc;        /*  Device context handle. */
HRGN     hrgn;       /*  Region handle. */
PVOID    pInstance;  /*  Pointer to instance data. */
ULONG    lFunction;  /*  High-order WORD=flags; low-order WORD=NGreSelectPathRegion. */
BOOL     fSuccess;   /*  Return codes. */

fSuccess = GreSelectPathRegion(hdc, hrgn,
             pInstance, lFunction);
