- I'm working on a project involving Wollengong TCP software - my
- project sits in between the Wollengong master server and the
- Wollengong daemons (rlogind, tftpd, etc.) The master server
- starts up my project instead of the daemon, then my project
- starts the daemon. My project makes the connection so the daemon
- can communicate.
-
- I have an echo daemon that was written and compiled locally. It
- works fine when running off the master server alone, and works
- also with my project in between. So, the project works, to an extent;
- with regard to the echo daemon, the connection is made, no problem.
-
- The problem: when my project starts a Wollengong daemon, the daemon
- exits immediately, with what I believe is an Access Violation error.
- The daemon is being started with sys$creprc, and I provide a mailbox
- to write to after the process terminates. Reading the mailbox with
- sys$qiow, I get the accounting message from the daemons termination,
- and the final status field is (hex) 1000000C. Since the C (dec 12)
- is listed as an Access Violation, I assume that's the error, but
- that 1 way over there makes me wonder, and I don't find any error
- codes that large.
-
- I don't have access to the source for the daemon, and the daemon
- works fine without my project in there. I guess the question is
- what are causes for Access Violation errors? I understand that
- they are actually fairly generic. Why does it work with our local
- echo daemon (which works with the master server alone, without
- my project), and not work with Wollengong daemons? Anyone have
- experience with this?
-
- Thanks,
