- ;; Notes on TCP package:
- ;;
- ;; This package provides a TCP/IP stream emulation on GNU Emacs. If
- ;; the function `open-network-stream' is not defined in Emacs, but
- ;; your operating system has a capability of network stream
- ;; connection, this tcp package can be used for communicating with
- ;; NNTP server.
- ;;
- ;; The tcp package runs inferior process named `tcp' which actually
- ;; does the role of `open-network-stream'. Before loading the package,
- ;; compile `tcp.c' and install it as `tcp' in a direcotry in the emacs
- ;; search path. If you modify `tcp.c', please send diffs to the author
- ;; of GNUS. I'll include some of them in the next releases.

- "Open a TCP connection for a service to a host.
- Returns a subprocess-object to represent the connection.
- Input and output work as for subprocesses; `delete-process' closes it.
- Args are NAME BUFFER HOST SERVICE.
- NAME is name for process. It is modified if necessary to make it unique.
- BUFFER is the buffer (or buffer-name) to associate with the process.
- Process output goes at end of that buffer, unless you specify
- an output stream or filter function to handle the output.
- BUFFER may be also nil, meaning that this process is not associated
- with any buffer
- Third arg is name of the host to connect to.
- Fourth arg SERVICE is name of the service desired, or an integer
- specifying a port number to connect to."
