· hdc
Identifies the device context.
· hrgn
Identifies an existing region before the function is called. After the function returns, this parameter identifies a copy of the current clipping region. |
An application-defined clipping region is a clipping region identified by the SelectClipRgn function. It is not a clipping region created when the application calls the BeginPaint function.
If the function succeeds, the hrgn parameter identifies a copy of the current clipping region. Subsequent changes to this copy will not affect the current clipping region. |
