GreGetArcParameters

GreGetArcParameters stores the current arc parameters in the buffer addressed by pArcParms.

This function can be hooked by the presentation driver.


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

Syntax
GreGetArcParameters(hdc, pArcParms, pInstance, lFunction);

Parameters

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


 * pArcParms (PARCPARAMS) - input
 * Pointer to ARCPARAMS structure.


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


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

Returns

 * 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_HDC_BUSY
 * PMERR_INV_HDC


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

Sample

 * 1) define INCL_GRE_ARCS
 * 2) include 

HDC          hdc;        /*  Device context handle. */ PARCPARAMS   pArcParms;  /*  Pointer to ARCPARAMS structure. */ PVOID        pInstance;  /*  Pointer to instance data. */ ULONG        lFunction;  /*  High-order WORD=flags; low-order WORD=NGreGetArcParameters. */ BOOL         fSuccess;   /*  Return codes. */

fSuccess = GreGetArcParameters(hdc, pArcParms,            pInstance, lFunction);
