26*33de042dSApple OSS Distributions<h3>DESCRIPTION</h3>
27*33de042dSApple OSS Distributions<p>
28*33de042dSApple OSS DistributionsThe <strong>memory_object_default_server</strong> function is the MIG generated server
29*33de042dSApple OSS Distributionshandling function to handle messages from the kernel targeted to the default
30*33de042dSApple OSS Distributionsmemory manager.  This server function only handles messages unique
31*33de042dSApple OSS Distributionsto the default
32*33de042dSApple OSS Distributionsmemory manager.  Messages that are common to all memory managers are
33*33de042dSApple OSS Distributionshandled by <strong>memory_object_server</strong>.
34*33de042dSApple OSS Distributions<p>
35*33de042dSApple OSS DistributionsA \*Vmemory manager\*O
36*33de042dSApple OSS Distributionsis a server task that responds to specific messages from the
37*33de042dSApple OSS Distributionskernel in order to handle memory management functions for the kernel.  The
38*33de042dSApple OSS Distributions<strong>memory_object_default_server</strong> function performs all necessary argument
39*33de042dSApple OSS Distributionshandling for a kernel message and calls one of the default memory manager
40*33de042dSApple OSS Distributionsfunctions.
41*33de042dSApple OSS Distributions<h3>RETURN VALUES</h3>
42*33de042dSApple OSS Distributions<dl>
43*33de042dSApple OSS Distributions<p>
44*33de042dSApple OSS Distributions<dt> <strong>TRUE</strong>
45*33de042dSApple OSS Distributions<dd>
46*33de042dSApple OSS DistributionsThe message was handled and the appropriate function was called.
47*33de042dSApple OSS Distributions<p>
48*33de042dSApple OSS Distributions<dt> <strong>FALSE</strong>
49*33de042dSApple OSS Distributions<dd>
50*33de042dSApple OSS DistributionsThe message did not apply to this memory management interface and
51*33de042dSApple OSS Distributionsno other action was taken.
