Remarks

Processes issuing MouDeRegister calls must conform to the following rules:

  • 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.
