notificationID: The ID of the kernel notification you want to add to..
anID: The ID of the simple notification (semaphore, message group, or event group) you want to add to the kernel notification.
notifyParam1: If anID specifies an event group, this parameter should contain the flags to set in the event group when MPCauseNotification is called. If anID specifies a message queue, this parameter should contain the first 32-bits of the message to be sent to the message queue when MPCauseNotification is called.
notifyParam2: If anID specifies a message queue, this parameter should contain the second 32-bits of the message to be sent to the message queue when MPCauseNotification is called. Pass NULL if you don’t need this parameter.
notifyParam3: If anID specifies a message queue, this parameter should contain the third 32-bits of the message sent to the message queue when MPCauseNotification is called. Pass NULL if you don’t need this parameter.

function result: A result code.
