A TCP connection is established by a +passive socket (the server) accepting a connection setup request from an +active socket (the client). Typically, the server binds its socket to a +well-known port with :ref:`PR_Bind`, calls :ref:`PR_Listen` to start listening +for connection setup requests, and calls :ref:`PR_Accept` to accept a +connection. The client makes a connection request using :ref:`PR_Connect`. + +After a connection is established, the client and server may send and +receive data between each other. To receive data, one can call +:ref:`PR_Read` or :ref:`PR_Recv`. To send data, one can call :ref:`PR_Write`, +:ref:`PR_Writev`, :ref:`PR_Send`, or :ref:`PR_TransmitFile`. :ref:`PR_AcceptRead` is +suitable for use by the server to accept a new client connection and +read the client's first request in one function call. + +A TCP connection can be shut down by :ref:`PR_Shutdown`, and the sockets +should be closed by :ref:`PR_Close`. + + +See Also +-------- + +:ref:`PR_NewTCPSocket` is deprecated because it is hardcoded to create an +IPv4 TCP socket. New code should use :ref:`PR_OpenTCPSocket` instead, which +allows the address family (IPv4 or IPv6) of the new TCP socket to be +specified. -- cgit v1.2.3
