26*19c3b8c2SApple OSS Distributions<h3>DESCRIPTION</h3>
27*19c3b8c2SApple OSS Distributions<p>
28*19c3b8c2SApple OSS DistributionsThe <strong>memory_object_default_server</strong> function is the MIG generated server
29*19c3b8c2SApple OSS Distributionshandling function to handle messages from the kernel targeted to the default
30*19c3b8c2SApple OSS Distributionsmemory manager.  This server function only handles messages unique
31*19c3b8c2SApple OSS Distributionsto the default
32*19c3b8c2SApple OSS Distributionsmemory manager.  Messages that are common to all memory managers are
33*19c3b8c2SApple OSS Distributionshandled by <strong>memory_object_server</strong>.
34*19c3b8c2SApple OSS Distributions<p>
35*19c3b8c2SApple OSS DistributionsA \*Vmemory manager\*O
36*19c3b8c2SApple OSS Distributionsis a server task that responds to specific messages from the
37*19c3b8c2SApple OSS Distributionskernel in order to handle memory management functions for the kernel.  The
38*19c3b8c2SApple OSS Distributions<strong>memory_object_default_server</strong> function performs all necessary argument
39*19c3b8c2SApple OSS Distributionshandling for a kernel message and calls one of the default memory manager
40*19c3b8c2SApple OSS Distributionsfunctions.
41*19c3b8c2SApple OSS Distributions<h3>RETURN VALUES</h3>
42*19c3b8c2SApple OSS Distributions<dl>

44*19c3b8c2SApple OSS Distributions<dt> <strong>TRUE</strong>
45*19c3b8c2SApple OSS Distributions<dd>
46*19c3b8c2SApple OSS DistributionsThe message was handled and the appropriate function was called.
47*19c3b8c2SApple OSS Distributions<p>
48*19c3b8c2SApple OSS Distributions<dt> <strong>FALSE</strong>
49*19c3b8c2SApple OSS Distributions<dd>
50*19c3b8c2SApple OSS DistributionsThe message did not apply to this memory management interface and
51*19c3b8c2SApple OSS Distributionsno other action was taken.
