    1.42 +
    1.43 +Provides transport services to a single protocol. Several of the calls to
    1.44 +CServProviderBase have pre-conditions attached to them - for example
    1.45 +a connection oriented protocol must have its local address set (either by
    1.46 +a SetLocalName() or AutoBind()) before it is opened. If the socket server
    1.47 +calls the CServProviderBase in such an erroneous way, the protocol should panic.
    1.48 +
    1.49 +It also provides an interface towards subconnection providers to allow
    1.50 +SAPs to work with a seperate control path.
