GreSelectPathRegion

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.


 * Simulation support: This function is simulated by a handling routine in the graphics engine.

Syntax
GreSelectPathRegion(hdc, hrgn, pInstance, lFunction);

Parameters

 * hdc (HDC) - input
 * Device context handle.


 * hrgn (HRGN) - input
 * Region handle.


 * pInstance (PVOID) - input
 * Pointer to instance data.


 * lFunction (ULONG) - input
 * High-order WORD=flags; low-order WORD=NGreSelectPathRegion.

Return Code

 * fSuccess (BOOL) - returns
 * Return codes.


 * This function returns BOOLEAN (fSuccess).


 * TRUE Successful
 * FALSE Error


 * Possible Errors Detected:  When an error is detected, the handling routine must call WinSetErrorInfo to post the condition. Error codes for conditions that the handling routine is expected to check include:


 * PMERR_DEV_FUNC_NOT_INSTALLED
 * PMERR_HDC_BUSY
 * PMERR_HRGN_BUSY
 * PMERR_INSUFFICIENT_MEMORY
 * PMERR_INV_COORDINATE
 * PMERR_INV_HDC
 * PMERR_INV_HRGN
 * PMERR_INV_RECT
 * PMERR_INV_REGION_CONTROL
 * PMERR_REGION_IS_CLIP_REGION


 * Refer to the "Error Explanations" section in the Presentation Manager Programming Reference for further explanation.

Declaration



 * 1) define INCL_GRE_CLIP
 * 2) include 

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);
