Is there a way to find out which fds to close, or should a function just close everything from, say, 3 to <some value> (assuming that 0, 1, and 2 are stdin, stdout, and stderr)? I could think of non-portable ways like looking under /proc/<pid>/fd, but I was wondering if the backend keeps track of its fds somewhere.
