  26 <h3>DESCRIPTION</h3>
  27 <p>
  28 The <strong>memory_object_default_server</strong> function is the MIG generated server
  29 handling function to handle messages from the kernel targeted to the default
  30 memory manager.  This server function only handles messages unique
  31 to the default
  32 memory manager.  Messages that are common to all memory managers are
  33 handled by <strong>memory_object_server</strong>.
  34 <p>
  35 A \*Vmemory manager\*O
  36 is a server task that responds to specific messages from the
  37 kernel in order to handle memory management functions for the kernel.  The
  38 <strong>memory_object_default_server</strong> function performs all necessary argument
  39 handling for a kernel message and calls one of the default memory manager
  40 functions.
  41 <h3>RETURN VALUES</h3>
  42 <dl>
  43 <p>
  44 <dt> <strong>TRUE</strong>
  45 <dd>
  46 The message was handled and the appropriate function was called.
  47 <p>
  48 <dt> <strong>FALSE</strong>
  49 <dd>
  50 The message did not apply to this memory management interface and
  51 no other action was taken.
