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

    #include <os2.h>

    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);
