Subject: Spawning a subprocess and communicating with it. Date: 1998/10/01 Message-ID: #1/1 X-Deja-AN: 396863851 Sender: Ada programming language Comments: Gated by NETNEWS@AUVM.AMERICAN.EDU Content-Type: text/plain MIME-Version: 1.0 Newsgroups: comp.lang.ada Date: 1998-10-01T00:00:00+00:00 List-Id: I'm looking for an example of how I might accomplish the following using SunOS 5.5.1 Unix and GNAT 3.9 (or later): I want to write an Ada program that can start up another Ada program as a subprocess, coprocess or whatever is the common Unix paradigm. (I just need it running as a separate, stand-alone executable image whose execution need go on no longer than that of the parent program that initiated it.) When the subprocess is up and running, I need to trade messages back and forth (character strings are sufficient) between the two processes. I presume this is all doable through various Unix system calls, but unfortunately, we don't seem to have anyone around here who is much of an expert on Unix calls, or how to interface to them via Ada or even any manuals one might peruse on the subject. If someone could send me a small example of how this is done, I would be grateful. Thanks. MDC Marin D.
