Not according to 'man 2 close'.
That only allows EBADF and EINTR (presumably for blocking close on
character devices, sockets and? pipes).
Most programs wouldn't want an fd left open just because a file was NFS
and a write generated by close failed.
This ought to be similar to what happens with stdio buffering.
Where, if you wan't to know whether the writes actually completed,
you have to call fflush() and ferror() prior to fclose().
