;; Notes on TCP package:
|
|
;;
|
|
;; This package provides a TCP/IP stream emulation for 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 which actually does the role
|
|
;; of `open-network-stream'. The program `tcp' provided with this
|
|
;; package can be used for such purpose. Before loading the package,
|
|
;; compile `tcp.c' and install it as `tcp' in a directory 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.
|
|
|
|
;;; Code:
|
|
|
|
(provide 'tcp)
|
|
|
|
(defvar tcp-program-name "tcp"
|
|
"*The name of the program emulating open-network-stream function.")
|
|
|
|
(defun open-network-stream (name buffer host service)
|
|
"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."
