GetClipRgn

Windows Mobile 6.5
A version of this page is also available for
4/8/2010

This function retrieves a handle identifying the current application-defined clipping region for the specified device context.


int GetClipRgn(
  HDC hdc, 
  HRGN hrgn
); 
hdc

[in] Handle to the device context.

hrgn

[in, out] Handle to an existing region before the function is called.

After the function returns, this parameter is a handle to a copy of the current clipping region.

If there is no clipping region for the specified device context, zero indicates success.

If there is a clipping region for the specified device context, 1 indicates success.

–1 indicates that an error occurred.

To get extended error information, call GetLastError.

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 is a handle to a copy of the current clipping region. Subsequent changes to this copy will not affect the current clipping region.
