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.

Bindings
