The EqualRgn function checks the two specified regions to determine whether they are identical. The function considers two regions identical if they are equal in size and shape.
BOOL EqualRgn(
|
HRGN hSrcRgn1, |
// handle to first region |
|
HRGN hSrcRgn2 |
// handle to second region |
|
); |
If the two regions are equal, the return value is nonzero.
If the two regions are not equal, the return value is zero. A return value of ERROR means at least one of the region handles is invalid.
