Parameters
N/A
Return Code
;rc (USHORT) - return:Return code descriptions are: * 0 NO_ERROR * 385 ERROR_MOUSE_NO_DEVICE * 416 ERROR_MOUSE_DEREGISTER * 466 ERROR_MOU_DETACHED * 505 ERROR_MOU_EXTENDED_SG
Remarks
Processes issuing MouDeRegister calls must conform to the following rules: *The process that issued the MouRegister must release the session (by a MouDeRegister) from the registered subsystem before another PID may issue MouRegister. *The process that issued the MouRegister is the only process that may issue MouDeRegister against the currently registered subsystem. *After the owning process has released the subsystem with a MouDeRegister, any other process in the session may issue a MouRegister and therefore modify the mouse support for the entire session.
