rc (USHORT) - return Return code descriptions are:

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.
