p The .Fn mvscanw and .Fn mvwscanw functions are the same as the .Fn scanw and .Fn mvscanw functions, respectively, excepting that .Fn wmove is called to move the cursor to the position specified by .Fa y , .Fa x before the data is read from the window. .Sh RETURN VALUES Functions returning pointers will return .Dv NULL if an error is detected. The functions that return an int will return one of the following values:
