25*5e3eaea3SApple OSS Distributions<h3>DESCRIPTION</h3>
26*5e3eaea3SApple OSS Distributions<p>
27*5e3eaea3SApple OSS DistributionsThe <strong>seqnos_notify_server</strong> function is the MIG generated server handling
28*5e3eaea3SApple OSS Distributionsfunction to handle messages from the kernel corresponding to IPC notifications.
29*5e3eaea3SApple OSS DistributionsSuch messages are delivered to the notification port named in a
30*5e3eaea3SApple OSS Distributions<strong>mach_msg</strong> or <strong>mach_port_request_notification</strong> call.
31*5e3eaea3SApple OSS DistributionsThe <strong>seqnos_notify_server</strong> function
32*5e3eaea3SApple OSS Distributionsperforms all necessary argument handling for this kernel message and calls the
33*5e3eaea3SApple OSS Distributionsappropriate handling function.  These functions must be supplied by the caller.
34*5e3eaea3SApple OSS Distributions<h3>NOTES</h3>
35*5e3eaea3SApple OSS Distributions<p>
36*5e3eaea3SApple OSS Distributions<strong>seqnos_notify_server</strong> differs from <strong>notify_server</strong>
37*5e3eaea3SApple OSS Distributionsin that it supplies message
38*5e3eaea3SApple OSS Distributionssequence numbers to the server interfaces.
39*5e3eaea3SApple OSS Distributions<h3>RETURN VALUES</h3>
40*5e3eaea3SApple OSS Distributions<dl>
41*5e3eaea3SApple OSS Distributions<p>
42*5e3eaea3SApple OSS Distributions<dt> <strong>TRUE</strong>
43*5e3eaea3SApple OSS Distributions<dd>
44*5e3eaea3SApple OSS DistributionsThe message was handled and the appropriate function was called.
45*5e3eaea3SApple OSS Distributions<p>
46*5e3eaea3SApple OSS Distributions<dt> <strong>FALSE</strong>
47*5e3eaea3SApple OSS Distributions<dd>
48*5e3eaea3SApple OSS DistributionsThe message did not apply to the notification mechanism and no other
49*5e3eaea3SApple OSS Distributionsaction was taken.
