Request from control side (at network layer) to indicate that the SubConnection is up and running and that we should bind to a Flow below.

Do the actual no Bearer call.

Performs some protocol specific IO control.

Upcall from protocol indicating no underlying bearer for the socket.

Tells the protocol to start waiting for an incoming connection request on this socket (i.e. port). It is called by the socket server in response to a listen request from a client.

Only ever called on connection-oriented sockets. Such a socket should always have both the local address and the remote address specified before this function is called. If this is not the case, then the protocol should panic.

The aQue parameter is the number of sockets which can be waiting for an outstanding Start after calling ConnectComplete(). The protocol should keep a count of sockets in this state - incrementing a variable in ConnectComplete(), and decrementing it in Start().

When a connection has completed, the protocol should call ConnectComplete() on its TNotify. If an error occurs during connection the protocol should not call ConnectComplete() at all; instead it should call Error().

Ask the SAP provider to perform a security policy check on the client process (default implementation).

Sets the local name (address) of the socket service provider entity. The format of the data in the TSockAddr object is defined by individual protocols.

Sets some protocol specific option when called by the socket server on behalf of a client. A protocol may pass the request down a protocol stack (to protocols it is bound to) using the SetOption() function of CProtocolBase.

Sets the remote name (address) of the socket service provider entity. The format of the data in the TSockAddr object is defined by individual protocols.

Terminates a connection (or closes a non connection-oriented socket down).

The value of the option argument specifies the type of processing which will be required of the protocol after this function is called.

Normally, when the socket server has called Shutdown() for a socket, it will wait for the socket to call CanClose() before destroying the CServProviderBase object. However, if the option argument is EImmediate, the CServProviderBase will be destroyed as soon as Shutdown() returns.

Start a service provider.

Sends data onto the network via the protocol.

Connection-oriented sockets must be in a connected state (that is ConnectComplete() has been called on their MSocketNotify before Write() is called).

The socket server keeps track of how much data is waiting and then tries to send it all until the protocol tells it to hold off by returning 0 (datagram sockets) or 'less than all data consumed' (stream sockets) to Write(). The protocol should call CanSend() when it is ready to send more data.

anAddr is the address to write the data to. Connection oriented sockets always use the default value.
