GreSetDefaultArcParameters

GreSetDefaultArcParameters sets the arc parameters to the default values.

This function is supported by the graphics engine.

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

Parameters

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


 * pArcParms (PARCPARAMS) - input
 * Pointer to the default arc parameters.


 * Pointer to an ARCPARAMS structure:
 * lP P coefficient
 * lQ Q coefficient
 * lR R coefficient
 * lS S coefficient


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


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

Return Code

 * fSuccess (BOOL) - returns
 * Return codes.


 * On completion, the handling routine must return BOOLEAN (fSuccess).


 * TRUE Successful
 * FALSE Error


 * Possible Errors Detected:  When an error is detected, the graphics engine calls WinSetErrorInfo to post the condition. Reasons for failure of this function include:


 * PMERR_HDC_BUSY
 * PMERR_INV_HDC


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

Sample Code

 * 1) define INCL_GRE_DEVSUPPORT
 * 2) include 

HDC          hdc;        /*  Device context handle. */ PARCPARAMS   pArcParms;  /*  Pointer to the default arc parameters. */ PVOID        pInstance;  /*  Pointer to instance data. */ ULONG        lFunction;  /*  High-order WORD=flags; low-order WORD=NGreSetDefaultArcParameters. */ BOOL         fSuccess;   /*  Return codes. */

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