    HDC       hdc;        /*  The device context handle. */

    LONG      cbVmem;

    PULONG    pReserved;  /*  A reserved pointer. Must be zero. */

    PVOID     pInstance;  /*  A pointer to instance data. */

    ULONG     lFunction;  /*  High-order WORD=flags; low-order WORD=NGreResurrection. */

    LONG      lResult;    /*  Return codes. */

    lResult = GreResurrection(hdc, cbVmem, pReserved,
