From Tru64's write(2):

[ENOSPC]     [XSH4.2]  No free space is left on the file system containing the     file.     [Tru64 UNIX]  An attempt
wasmade to write past the "early     warning" EOT while this indicator was enabled.     [Tru64 UNIX]  An attempt was
madeto write at or beyond the end of     a partition.
 

From close(2):

[Tru64 UNIX]   A close() function on an NFS file system waits for all
outstanding I/O to complete. If any operation completes with an error,
the error will be returned by close(). The possible errors depend on the
NFS server implementation, but the most likely errors are:

[ENOSPC] Attempted to write on a full file system.

You always need to check the return codes of calls like that, what if
you received EBADF or EINTR for whatever reason?
