Casting to LPPOINT

Is casting a POINT argument to LPPOINT needed or not in the following scenario:

POINT point;
ClientToScreen(somehwnd, (LPPOINT) &point);

Or is the following enough:

POINT point;
ClientToScreen(somehwnd, &point);

This Win32 document uses a cast, whereas this Win32 document does not use a cast.

>Solution :

LPPOINT is a type alias for POINT*. The expression &point has the type POINT*. A cast is not required.
