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.

• 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
