Simulation support:

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

Description

GreModifyPath modifies a path. When the transform is singular, GreModifyPath is invalid and causes an error to be logged.

This function can be hooked by the presentation driver.

#define INCL_GRE_PATHS

HDC      hdc;        /*  Device context handle. */
LONG     idPath;     /*  Path ID. */

PVOID    pInstance;  /*  Pointer to instance data. */
ULONG    lFunction;  /*  High-order WORD=flags; low-order WORD=NGreModifyPath. */
BOOL     fSuccess;   /*  Return codes. */

fSuccess = GreModifyPath(hdc, idPath, cmdMode,
             pInstance, lFunction);
