index_ specifies the index of the file descriptor to get. It is a
programmer error for index_ to be out of range; see
gio.unix_fdlist.UnixFDList.getLength.
The file descriptor is duplicated using dup() and set as
close-on-exec before being returned. You must call close() on it
when you are done.
A possible cause of failure is exceeding the per-process or
system-wide file descriptor limit.
