26*2c2f96dcSApple OSS Distributions<h3>DESCRIPTION</h3>
27*2c2f96dcSApple OSS Distributions<p>
28*2c2f96dcSApple OSS DistributionsThe <strong>memory_object_server</strong> function is the MIG generated
29*2c2f96dcSApple OSS Distributionsserver handling
30*2c2f96dcSApple OSS Distributionsfunction to handle messages from the kernel targeted to a memory manager.
31*2c2f96dcSApple OSS Distributions<p>
32*2c2f96dcSApple OSS DistributionsA \*Vmemory manager\*O
33*2c2f96dcSApple OSS Distributionsis a server task that responds to specific messages from the
34*2c2f96dcSApple OSS Distributionskernel in order to handle memory management functions for the kernel.  The
35*2c2f96dcSApple OSS Distributions<strong>memory_object_server</strong> function performs all necessary
36*2c2f96dcSApple OSS Distributionsargument handling for
37*2c2f96dcSApple OSS Distributionsa kernel message and calls one of the memory manager functions to interpret
38*2c2f96dcSApple OSS Distributionsthe message.
39*2c2f96dcSApple OSS Distributions<h3>RETURN VALUES</h3>
40*2c2f96dcSApple OSS Distributions<dl>
41*2c2f96dcSApple OSS Distributions<p>
42*2c2f96dcSApple OSS Distributions<dt> <strong>TRUE</strong>
43*2c2f96dcSApple OSS Distributions<dd>
44*2c2f96dcSApple OSS DistributionsThe message was handled and the appropriate function was called.
45*2c2f96dcSApple OSS Distributions<p>
46*2c2f96dcSApple OSS Distributions<dt> <strong>FALSE</strong>
47*2c2f96dcSApple OSS Distributions<dd>
48*2c2f96dcSApple OSS DistributionsThe message did not apply to this memory management interface and
49*2c2f96dcSApple OSS Distributionsno other action was taken.
