# Module proc_socket_server # * [Description](#description) * [Function Index](#index) * [Function Details](#functions)

Keeps track of a number of TCP sessions.

This module will manage a collection of TCP sessions for the same
server.  If +Port+ is 0, the underlying OS assigns an available
port number.  If a +Name+ is not specified, the server will be
named +picoSocketServer_+ plus the TCP port number that the
service listens to, e.g. +picoSocketServer_9923+.
A managed server can be started, stopped, enumerate child
sessions, and limit the maximum number of child sessions.
The conventions used by this module look quite different than
OTP-based services, due to its origin.

Start a new UBF contract-using server.

  • This server accepts up to Max connections on TCP port Port.

  • SpawnOpts are the erlang garbage collection options for the spawned process.

  • Each time a new connection is made, Fun(Socket) is called.

    ------
    Fun = fun(Socket) -> exit(normal) | exit(socket_closed) |
                         exit({socket_error, Reason}) | exit(timeout).
    ------
    Fun will handle all of the protocol communication for a single TCP
    session.
    A raw server uses packet length 0 (see start_raw_server/5 and
    start_raw_server/7).
