GreSetArcParameters sets the arc parameters.
This function can be hooked by the presentation driver.
- Simulation support
- This function is simulated by a handling routine in the graphics engine.
Syntax
GreSetArcParameters(hdc, pArcParms, pInstance, lFunction)
Parameters
- hdc (HDC) - input
- Device context handle.
- pArcParms (PARCPARAMS) - input
- Pointer to an array containing the arc parameters.
- See the Presentation Manager Programming Reference for a full description of the arc parameters structure.
- pInstance (PVOID) - input
- Pointer to instance data.
- lFunction (ULONG) - input
- High-order WORD=flags; low-order WORD=NGreSetArcParameters.
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.
