I only catch real process id. In practice we don't have processes with negative pid_t, do we? I can't find any document about this, but at least waitpid seems to treat negative pid (except -1) just as an indicator while the true pid is the positive counterpart. > fork() returns -1 on failure, and its return type is pid_t. i don't > know what fantasy unix system has an unsigned pid_t -- Duy -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
