  13 <p>
  14 <dt> <var>in_msg</var>
  15 <dd>
  16 [pointer to in structure]
  17 The memory manager message received from
  18 the kernel.

  20 <dt> <var>out_msg</var>

  26 <h3>DESCRIPTION</h3>
  27 <p>
  28 The <strong>seqnos_memory_object_default_server</strong> function is
  29 the MIG generated
  30 server handling function to handle messages from the kernel targeted to the
  31 default memory manager.  This server function only handles messages unique to
  32 the default memory manager.  Messages that are common to all memory
  33 managers are handled by <strong>seqnos_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>seqnos_memory_object_default_server</strong> function performs all necessary
  39 argument handling for a kernel message and calls one of the default memory
  40 manager functions.
  41 <h3>NOTES</h3>
  42 <p>
  43 <strong>seqnos_memory_object_default_server</strong> differs from
  44 <strong>memory_object_default_server</strong> in that it supplies message
  45 sequence numbers to the server
  46 interfaces it calls.
  47 <h3>RETURN VALUES</h3>
  48 <dl>
  49 <p>
  50 <dt> <strong>TRUE</strong>
  51 <dd>
  52 The message was handled and the appropriate function was called.
  53 <p>
  54 <dt> <strong>FALSE</strong>
  55 <dd>
  56 The message did not apply to this memory management interface and
  57 no other action was taken.
