static WINGDIAPI int WINAPI GetClipRgn_I(HDChdc, HRGNhrgn);
Parameters
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 the specified device context has no clipping region, zero indicates success.
If the specified device context has a clipping region, 1 indicates success.
–1 indicates that an error occurred.

Remarks
This method is an internal version of the GetClipRgn function.
An application-defined clipping region is a clipping region identified by the Gdi::SelectClipRgn_I method. An application-defined clipping region is not a clipping region created when the application calls the GweBypassCoredllThunk_t::BeginPaint_I method.
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.
Requirements
OS Versions: Windows CE .NET 4.0 and later.
Header: Gdi.hpp.
