Not on most systems. Reaching a ulimit -n limit usually causes open(2)
to fail with EMFILE (Too many open files) rather than ENOSPC (No space
left on device). ENOSPC is only supposed to be returned if the
filesystem has either run out of space altogether, or has run out of
inodes. (Incidentally, going over quota on a filesystem also has its own
errno, EDQUOT (Quota exceeded).)

However, check your system documentation, because some systems do
strange things.
