that's a possibility but I personally thing the huge difference in
efficiency
makes it worth putting it in the kernel.
Quite a few programs I know of could really help their startup time with
this as the first thing they do is "close the first 2000 file descriptors.
Woops! Sorry for responding this late, but it looks like I didn't
explain myself good enough. Sorry. :) To rephrase myself:
Wouldn't it be better to just implement fcntl(..., F_CLOSEM, ...) in the
kernel and make closefrom() a simple libc routine:
void
closefrom(int lowfd)
{
fcntl(lowfd, F_CLOSEM, NULL);
}
what on earth would that achieve?
(as opposed to just a simple syscall)
Similar to creat(2).
