NMRemove

To remove a notification request, use the NMRemove function.

FUNCTION NMRemove (nmReqPtr: NMRecPtr): OSErr;

nmReqPtr

A pointer to a notification record.

DESCRIPTION

The NMRemove function removes the notification request identified by the nmReqPtr parameter from the notification queue and returns a result code.
