### GreFillPath - Syntax

Simulation support:

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

Description

GreFillPath fills the interior of the closed figure defined in the path by using the current pattern attributes. Before filling the path, the handling routine must close any open figures in the path definition. On completion, it must delete the path. All of the boundaries of the area are considered to be part of the interior and are filled.

This function can be hooked by the presentation driver.

    #define INCL_GRE_PATHS

    #include <os2.h>

    HDC      hdc;        /*  Device context handle. */

    LONG     idPath;     /*  Path ID.  It must be 1. */

    ULONG    flOptions;  /*  Option flags. */

    PVOID    pInstance;  /*  Pointer to instance data. */

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

    LONG     rc;         /*  Return codes. */

    rc = GreFillPath(hdc, idPath, flOptions, pInstance,
