GetMetaRgn function (wingdi.h)
The GetMetaRgn function retrieves the current metaregion for the specified device context.
C++
int GetMetaRgn(
[in] HDC hdc,
[in] HRGN hrgn
);
[in] hdc
A handle to the device context.
[in] hrgn
A 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 metaregion.
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero.
If the function succeeds, hrgn is a handle to a copy of the current metaregion. Subsequent changes to this copy will not affect the current metaregion.
The current clipping region of a device context is defined by the intersection of its clipping region and its metaregion.
