Simulation support:

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

Description

GreOffsetRegion moves the given region by the specified amounts (unless the region is in use as a clipping region when an error is raised).

This function can be hooked by the presentation driver.

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

fSuccess = GreOffsetRegion(hdc, hrgn, pdpt,
             pInstance, lFunction);
