GetMetaRgn
The GetMetaRgn
function retrieves the current metaregion for the specified device context.
int GetMetaRgn(
HDC hdc, |
// handle of device
context |
HRGN hrgn |
// handle of region
|
); |
|
Parameters
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 metaregion.
Return Values
If the
function succeeds, the return value is one.
If the
function fails, the return value is zero.
Remarks
If the
function succeeds, hrgn identifies 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.
