Deregisters a mouse subsystem or environment manager previously registered within a session.
Syntax
MouDeRegister ()
Parameters
None
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.
