26*19c3b8c2SApple OSS Distributions<h3>DESCRIPTION</h3>
27*19c3b8c2SApple OSS Distributions<p>
28*19c3b8c2SApple OSS DistributionsThe <strong>memory_object_server</strong> function is the MIG generated
29*19c3b8c2SApple OSS Distributionsserver handling
30*19c3b8c2SApple OSS Distributionsfunction to handle messages from the kernel targeted to a memory manager.
31*19c3b8c2SApple OSS Distributions<p>
32*19c3b8c2SApple OSS DistributionsA \*Vmemory manager\*O
33*19c3b8c2SApple OSS Distributionsis a server task that responds to specific messages from the
34*19c3b8c2SApple OSS Distributionskernel in order to handle memory management functions for the kernel.  The
35*19c3b8c2SApple OSS Distributions<strong>memory_object_server</strong> function performs all necessary
36*19c3b8c2SApple OSS Distributionsargument handling for
37*19c3b8c2SApple OSS Distributionsa kernel message and calls one of the memory manager functions to interpret
38*19c3b8c2SApple OSS Distributionsthe message.

46*19c3b8c2SApple OSS Distributions<dt> <strong>FALSE</strong>
47*19c3b8c2SApple OSS Distributions<dd>
48*19c3b8c2SApple OSS DistributionsThe message did not apply to this memory management interface and
49*19c3b8c2SApple OSS Distributionsno other action was taken.
