Getting Started with Sockets Over Local IPC

This section provides some basic information for getting started with sockets over Local IPC:

• Use PF_OS2, or PF_UNIX for the protocol family

• Use AF_OS2, or AF_UNIX for the address family

• The following socket types are supported for the Local IPC domain:

  • Datagram (SOCK_DGRAM)
    
  • Stream (SOCK_STREAM)
  The socket type is passed as a parameter to the socket() call. For additional information, see Socket Types.

A unique text string is used as a name. See Local IPC Address Format for details.

If a connect() socket call is received without an explicit bind() call, an implicit bind is automatically performed. The application can use any name, and a unique Local IPC name is generated by networking services. You can retrieve the Local IPC name by using the getsockname() call.
