From MSDN:
Quote:Sets the size of the work area. The work area is the portion of the screen not obscured by the system taskbar or by application desktop toolbars. The pvParam parameter is a pointer to a RECT structure that specifies the new work area rectangle, expressed in virtual screen coordinates. In a system with multiple display monitors, the function sets the work area of the monitor that contains the specified rectangle.
If pvParam is NULL, the function sets the work area of the primary display monitor to the full screen.
