Why not just pass it a string key rather than an int, ie
"\x0b\x0b..."? The manpage doesn't specifically say passing ints is

You can also use sysconf(3); I'm not sure if that's just a wrapper
around opening the /proc file.
If I was a user experiencing this, I don't think being told the
maximum number of files would be super helpful. Being told to look in
/proc/blah might be somewhat helpful. Being told which runaway
