File system + implementations which use techniques as ``write-behind'' + to increase performance may lead to write(2) succeeding, + although the data has not been written yet. The error + status may be reported at a later write operation, but it + is guaranteed to be reported on closing the file. Not + checking the return value when closing the file may lead + to silent loss of data. This can especially be observed + with NFS and disk quotas. + +</pre> +<hr> +<h3>SEE ALSO +</h3><p> +<a href=../FUNCTIONS/open.html>open</a>, +<a href=fcntl.htm>fcntl</a>, +<a href=shutdown.htm>shutdown</a>, +<a href=unlink.htm>unlink</a>, +<pre> + + + + + + + + + + + + + + + + + February 18, 1995 1 + + +
