BOOLUnionRect(LPRECTlprcDst, constRECT* lprcSrc1, constRECT* lprcSrc2);
Parameters
- lprcDst
Long pointer to the RECT structure that will receive a rectangle containing the rectangles pointed to by the lprcSrc1 and lprcSrc2 parameters. - lprcSrc1
Long pointer to the RECT structure that contains the first source rectangle. - lprcSrc2
Long pointer to the RECT structure that contains the second source rectangle.
Return Values
Nonzero indicates that the specified structure contains a nonempty rectangle.
Zero indicates that the specified structure does not contain a nonempty rectangle.
To get extended error information, call GetLastError.
Remarks
The system ignores the dimensions of an empty rectangle; that is, a rectangle in which all coordinates are set to zero, so it has no height or no width.
