Parameters
- lprcDst
Long pointer to the RECT structure that will receive a rectangle containing the rectangles pointed to by the lprcSrc1 and lprcSrc2 parameters.

Long pointer to the RECT structure that contains the first source rectangle.
- lprcSrc2

Return Value
Nonzero indicates that the specified structure contains a nonempty rectangle.
Zero indicates that the specified structure does not contain a nonempty rectangle.

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.
