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.
