[Info-vax] Help wanted : Porting code from Linux to VMS

[Marc Van Dyck]

My job today is mainly system administration. But I have done software
development in the past, and still enjoy doing some programming when 
the
opportunity arises. What I have been asked to do today is however a bit
more challenging for me than usual.

It'll basically consist of porting C code written for a linux platform
to OpenVMS. And it won't be the trivial 'copy the code and recompile'
job :

1) it contains several system calls which I'll need to find an adequate
equivalent for. I think I can manage that one, even if I know nothing
about Linux.

2) I will port the code from C to Pascal, which is the only language I
feel comfortable with. Not afraid by that one, have done it several
times already.

3) The code contains a good dose of TCP/IP programming. And there I'm
somewhat lost, because I never touched that in the past. So I'd
appreciate a bit of help to get me started...

Hence the following questions :

1) Is there any documentation about that ? How to write, on OpenVMS,
code to establish a TCP/IP communication with another host ? Like what
you would do with DECnet non transparent task to task communication ?

2) Any coding examples availabe somewhere, or that someone would agree
to share ? Preferably in Pascal, but I'll understand if only C is
available...

3) Are the TCP/IP calls definitions that I'll need to use available
in pascal environment files somewhere ? Or SDL definitions that I
could translate and compile ?

If you want to send me something, the address is
marc dot gr dot vandyck at skynet dot be.

Many thanks in advance for all your hints !
