The pointer display level determines whether the pointer is shown. If it is zero, the pointer is visible, but if it is greater than zero, the pointer is not visible. The initial setting of the pointer display level is dependent on the capabilities of the device. If a pointing device exists, the initial setting of the pointer display level is zero, otherwise it is one. The existing pointer display level can be obtained by using the WinQuerySysValue function with iSysValue set to SV_POINTERLEVEL.
