Re: fork, pipes, and Tiger

You have them backwards, which incorrectly assumes bidirectional pipes.

Hmm, I don't see this. In the code, "out=fromchild[IN]" is read and "in=tochild[OUT]" is written to, so this seems correct.

Either fix your code, or use socketpair() instead of pipe().

The code was originally written for linux, I am not the author, I am only trying to port it to Mac OSX. It never worked on OSX 10.1, because of double buffered stdout problems. On 10.2 it worked with a terrible hack, because the shell gave a spurious warning at each line, and this warning had to be discarded. On 10.3 it worked as it was supposed to, and now on 10.4 it is broken again.

I'll try to read about socketpair(), but I'd prefer not to have to rewrite the code too much.
