MouDeRegister

This call deregisters a mouse subsystem previously registered within a session.

Syntax

MouDeRegister ()

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.
