A quick guess: perhaps your parent process has elected for the kernel to automatically reap child processes, via a call similar to:

   signal(SIGCHLD, SIG_IGN);

I would expect the behavior you describe from waitpid() if the above functionality is enabled.

See http://en.wikipedia.org/wiki/SIGCHLD.

Thanks everyone for your help. If I remove signal(SIGCHLD, SIG_IGN) from the macfuse code my waitpid() starts working again as I expected. What macfuse does is some kind of "process demonization" and should be reimplemented without ignoring SIGCHLD in the parent process. Thanks. _______________________________________________ Do not post admin requests to the list. They will be ignored.
