cSave (LONG) - input
Indicates the saved DC state, which the handling routine uses to restore the path. When cSave is passed as 1, the handling routine resets the path 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 path is restored to its initial state. Other positive values identify which saved level is restored. See RestoreDCState.
