25*0f4c859eSApple OSS Distributions<h3>DESCRIPTION</h3>
26*0f4c859eSApple OSS Distributions<p>
27*0f4c859eSApple OSS DistributionsThe <strong>seqnos_notify_server</strong> function is the MIG generated server handling
28*0f4c859eSApple OSS Distributionsfunction to handle messages from the kernel corresponding to IPC notifications.
29*0f4c859eSApple OSS DistributionsSuch messages are delivered to the notification port named in a
30*0f4c859eSApple OSS Distributions<strong>mach_msg</strong> or <strong>mach_port_request_notification</strong> call.
31*0f4c859eSApple OSS DistributionsThe <strong>seqnos_notify_server</strong> function
32*0f4c859eSApple OSS Distributionsperforms all necessary argument handling for this kernel message and calls the
33*0f4c859eSApple OSS Distributionsappropriate handling function.  These functions must be supplied by the caller.
34*0f4c859eSApple OSS Distributions<h3>NOTES</h3>
35*0f4c859eSApple OSS Distributions<p>
36*0f4c859eSApple OSS Distributions<strong>seqnos_notify_server</strong> differs from <strong>notify_server</strong>
37*0f4c859eSApple OSS Distributionsin that it supplies message
38*0f4c859eSApple OSS Distributionssequence numbers to the server interfaces.
39*0f4c859eSApple OSS Distributions<h3>RETURN VALUES</h3>
40*0f4c859eSApple OSS Distributions<dl>
41*0f4c859eSApple OSS Distributions<p>

43*0f4c859eSApple OSS Distributions<dd>
44*0f4c859eSApple OSS DistributionsThe message was handled and the appropriate function was called.

46*0f4c859eSApple OSS Distributions<dt> <strong>FALSE</strong>
47*0f4c859eSApple OSS Distributions<dd>
48*0f4c859eSApple OSS DistributionsThe message did not apply to the notification mechanism and no other
49*0f4c859eSApple OSS Distributionsaction was taken.
