<dd>
[pointer to in structure]
The memory manager message received from 
the kernel.

<h3>DESCRIPTION</h3>
<p>
The <strong>memory_object_server</strong> function is the MIG generated
server handling 
function to handle messages from the kernel targeted to a memory manager.
<p>
A \*Vmemory manager\*O 
is a server task that responds to specific messages from the 
kernel in order to handle memory management functions for the kernel.  The 
<strong>memory_object_server</strong> function performs all necessary
argument handling for 
a kernel message and calls one of the memory manager functions to interpret 
the message.
<h3>RETURN VALUES</h3>
<dl>
<p>
<dt> <strong>TRUE</strong>
<dd>
The message was handled and the appropriate function was called.
<p>
<dt> <strong>FALSE</strong>
<dd>
The message did not apply to this memory management interface and 
no other action was taken.
