26*2c2f96dcSApple OSS Distributions<h3>DESCRIPTION</h3>
27*2c2f96dcSApple OSS Distributions<p>
28*2c2f96dcSApple OSS DistributionsThe <strong>memory_object_default_server</strong> function is the MIG generated server
29*2c2f96dcSApple OSS Distributionshandling function to handle messages from the kernel targeted to the default
30*2c2f96dcSApple OSS Distributionsmemory manager.  This server function only handles messages unique
31*2c2f96dcSApple OSS Distributionsto the default
32*2c2f96dcSApple OSS Distributionsmemory manager.  Messages that are common to all memory managers are
33*2c2f96dcSApple OSS Distributionshandled by <strong>memory_object_server</strong>.
34*2c2f96dcSApple OSS Distributions<p>
35*2c2f96dcSApple OSS DistributionsA \*Vmemory manager\*O
36*2c2f96dcSApple OSS Distributionsis a server task that responds to specific messages from the
37*2c2f96dcSApple OSS Distributionskernel in order to handle memory management functions for the kernel.  The
38*2c2f96dcSApple OSS Distributions<strong>memory_object_default_server</strong> function performs all necessary argument
39*2c2f96dcSApple OSS Distributionshandling for a kernel message and calls one of the default memory manager
40*2c2f96dcSApple OSS Distributionsfunctions.
41*2c2f96dcSApple OSS Distributions<h3>RETURN VALUES</h3>
42*2c2f96dcSApple OSS Distributions<dl>
43*2c2f96dcSApple OSS Distributions<p>
44*2c2f96dcSApple OSS Distributions<dt> <strong>TRUE</strong>
45*2c2f96dcSApple OSS Distributions<dd>
46*2c2f96dcSApple OSS DistributionsThe message was handled and the appropriate function was called.
47*2c2f96dcSApple OSS Distributions<p>
48*2c2f96dcSApple OSS Distributions<dt> <strong>FALSE</strong>
49*2c2f96dcSApple OSS Distributions<dd>
50*2c2f96dcSApple OSS DistributionsThe message did not apply to this memory management interface and
51*2c2f96dcSApple OSS Distributionsno other action was taken.
