Here is a simple little replacement for system() that does close file descriptors. The main issue with it is though, it ends up picking an arbitrary number of fds to close. I picked closing 0 to 99.
I don't think this is necessary. Every file descriptor has a "close on exec" flag that you can set with fcntl(). Then, you can use plain system(). It should work like this:
fcntl(fd, F_SETFD, FD_CLOEXEC); Ideally, one would do this for each file descriptor as it is opened. Hope this helps, chrisp -- chrisp a.k.a. Christoph Pfisterer "A computer scientist is c...@chrisp.de - http://chrisp.de someone who fixes things PGP key & geek code available that aren't broken."
