26*d8b80295SApple OSS Distributions<h3>DESCRIPTION</h3>
27*d8b80295SApple OSS Distributions<p>
28*d8b80295SApple OSS DistributionsThe <strong>seqnos_memory_object_default_server</strong> function is
29*d8b80295SApple OSS Distributionsthe MIG generated
30*d8b80295SApple OSS Distributionsserver handling function to handle messages from the kernel targeted to the
31*d8b80295SApple OSS Distributionsdefault memory manager.  This server function only handles messages unique to
32*d8b80295SApple OSS Distributionsthe default memory manager.  Messages that are common to all memory
33*d8b80295SApple OSS Distributionsmanagers are handled by <strong>seqnos_memory_object_server</strong>.
34*d8b80295SApple OSS Distributions<p>
35*d8b80295SApple OSS DistributionsA \*Vmemory manager\*O
36*d8b80295SApple OSS Distributionsis a server task that responds to specific messages from the
37*d8b80295SApple OSS Distributionskernel in order to handle memory management functions for the kernel.  The
38*d8b80295SApple OSS Distributions<strong>seqnos_memory_object_default_server</strong> function performs all necessary
39*d8b80295SApple OSS Distributionsargument handling for a kernel message and calls one of the default memory
40*d8b80295SApple OSS Distributionsmanager functions.
41*d8b80295SApple OSS Distributions<h3>NOTES</h3>
42*d8b80295SApple OSS Distributions<p>
43*d8b80295SApple OSS Distributions<strong>seqnos_memory_object_default_server</strong> differs from
44*d8b80295SApple OSS Distributions<strong>memory_object_default_server</strong> in that it supplies message
45*d8b80295SApple OSS Distributionssequence numbers to the server
46*d8b80295SApple OSS Distributionsinterfaces it calls.
47*d8b80295SApple OSS Distributions<h3>RETURN VALUES</h3>
48*d8b80295SApple OSS Distributions<dl>
49*d8b80295SApple OSS Distributions<p>
50*d8b80295SApple OSS Distributions<dt> <strong>TRUE</strong>
51*d8b80295SApple OSS Distributions<dd>
52*d8b80295SApple OSS DistributionsThe message was handled and the appropriate function was called.
53*d8b80295SApple OSS Distributions<p>
54*d8b80295SApple OSS Distributions<dt> <strong>FALSE</strong>
55*d8b80295SApple OSS Distributions<dd>
56*d8b80295SApple OSS DistributionsThe message did not apply to this memory management interface and
57*d8b80295SApple OSS Distributionsno other action was taken.
