GetMetaRgn function (wingdi.h)
The GetMetaRgn function retrieves the current metaregion for the specified device context.
Syntax
int GetMetaRgn(
[in] HDC hdc,
[in] HRGN hrgn
);
Parameters
[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.
Return value
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero.
Remarks
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.
