*Number of segment buffers available*

Type: ``int``

.. code-block:: none

    The incoming and outgoing segmented messages allocate their
    segments from the same pool. Each segment is a 12 byte block,
    and may only be used by one message at the time.

    Outgoing messages will allocate their segments at the start of the
    transmission, and release them one by one as soon as they have been
    acknowledged by the receiver. Incoming messages allocate all their
    segments at the start of the transaction, and won't release them until
    the message is fully received.
