26*0f4c859eSApple OSS Distributions<h3>DESCRIPTION</h3>
27*0f4c859eSApple OSS Distributions<p>
28*0f4c859eSApple OSS DistributionsThe <strong>memory_object_default_server</strong> function is the MIG generated server
29*0f4c859eSApple OSS Distributionshandling function to handle messages from the kernel targeted to the default
30*0f4c859eSApple OSS Distributionsmemory manager.  This server function only handles messages unique
31*0f4c859eSApple OSS Distributionsto the default
32*0f4c859eSApple OSS Distributionsmemory manager.  Messages that are common to all memory managers are
33*0f4c859eSApple OSS Distributionshandled by <strong>memory_object_server</strong>.
34*0f4c859eSApple OSS Distributions<p>
35*0f4c859eSApple OSS DistributionsA \*Vmemory manager\*O
36*0f4c859eSApple OSS Distributionsis a server task that responds to specific messages from the
37*0f4c859eSApple OSS Distributionskernel in order to handle memory management functions for the kernel.  The
38*0f4c859eSApple OSS Distributions<strong>memory_object_default_server</strong> function performs all necessary argument
39*0f4c859eSApple OSS Distributionshandling for a kernel message and calls one of the default memory manager
40*0f4c859eSApple OSS Distributionsfunctions.
41*0f4c859eSApple OSS Distributions<h3>RETURN VALUES</h3>
42*0f4c859eSApple OSS Distributions<dl>

44*0f4c859eSApple OSS Distributions<dt> <strong>TRUE</strong>
45*0f4c859eSApple OSS Distributions<dd>
46*0f4c859eSApple OSS DistributionsThe message was handled and the appropriate function was called.
47*0f4c859eSApple OSS Distributions<p>
48*0f4c859eSApple OSS Distributions<dt> <strong>FALSE</strong>
49*0f4c859eSApple OSS Distributions<dd>
50*0f4c859eSApple OSS DistributionsThe message did not apply to this memory management interface and
51*0f4c859eSApple OSS Distributionsno other action was taken.
