/**
|
||
|
* SendNotification
|
||
|
*
|
||
|
* Description:
|
||
|
* This function sends a broadcast message to the local machine. The
|
||
|
* message is specified by aMsgId. The parameter anInterval specifies
|
||
|
* the amount of time to wait between consecutive messages. If this
|
||
|
* value is zero the message is only sent once, otherwise the message
|
||
|
* will repeat until SendNotification(..) or CancelNotification() is
|
||
|
* called. aDelay specifies that the message should be send aDelay
|
||
|
* seconds in the future - note that this method will not block for aDelay
|
||
|
* seconds, it returns immediately and sends the message on a separate
|
||
|
* thread. Any current previously executing periodic notifications
|
||
|
* are canceled as a result of this call.
|
||
|
*
|
||
|
* This method also keeps track of whether the power out message had
|
||
|
* been sent to users. This is done in order to squelch a power return
|
||
|
* message if a power out message had not already been sent.
|
||
|
*
|
||
|
* Parameters:
|
||
|
* aMsgId - the message to send
|
||
|
* anInterval - the amount of time, in seconds, between messages
|
||
|
* aDelay - the amount of time, in seconds to wait to send message
|
||
|
*
|
||
|
* Returns:
|
||
|
* nothing
