hdc (HDC) - input

Device context handle.

cSave (LONG) - input

DC save level.

Indicates the saved DC state, which the handling routine uses to restore the transform. When cSave is passed as -1, the handling routine resets the transform to its initial state (-1 is passed to this routine from GreResetDC and is the only valid negative value). A value of 0 indicates that the transform is reset to its initial state. Other positive values identify which saved level is restored. See RestoreDCState.

pInstance (PVOID) - input

Pointer to instance data.

lFunction (ULONG) - input

High-order WORD=flags; low-order WORD=NGreRestoreXform.

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
