Re: piping to c

Hello. I have to write a pipe to joint a GUI in perl and a simulation
program in c. I have read all the docs found in perl.com and now I am
trying to make a test with this simple program. It seems working but it
does not write "bonjour" at the end. Can anybody tell me where my
mistake is? I will be happy for any sample of code for a pipe between c
and perl sent to me too.

Sorry, but you ended up in the wrong place. fork(), dup2() etc.
aren't (standard) C functions but UNIX extensions and for this
reason off-topic here. You will find a much more receptive
audience for your problems in e.g. comp.unix.programmer.

<OT>
You don't even create a pipe using pipe(), so there's no pipe to
write to at all, just an uninitialized array of two integers. And
on top of that you first write to pfd[1] before the dup2() to make
it the standard output of the program. But for more details please
ask in comp.unix.programmer.
