26*5e3eaea3SApple OSS Distributions<h3>DESCRIPTION</h3>
27*5e3eaea3SApple OSS Distributions<p>
28*5e3eaea3SApple OSS DistributionsThe <strong>memory_object_server</strong> function is the MIG generated
29*5e3eaea3SApple OSS Distributionsserver handling
30*5e3eaea3SApple OSS Distributionsfunction to handle messages from the kernel targeted to a memory manager.
31*5e3eaea3SApple OSS Distributions<p>
32*5e3eaea3SApple OSS DistributionsA \*Vmemory manager\*O
33*5e3eaea3SApple OSS Distributionsis a server task that responds to specific messages from the
34*5e3eaea3SApple OSS Distributionskernel in order to handle memory management functions for the kernel.  The
35*5e3eaea3SApple OSS Distributions<strong>memory_object_server</strong> function performs all necessary
36*5e3eaea3SApple OSS Distributionsargument handling for
37*5e3eaea3SApple OSS Distributionsa kernel message and calls one of the memory manager functions to interpret
38*5e3eaea3SApple OSS Distributionsthe message.
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 this memory management interface and
49*5e3eaea3SApple OSS Distributionsno other action was taken.
