<para>
If <parameter>handle</parameter> was <function>fopen</function>ed in
append mode, <function>fwrite</function>s are atomic (unless the size of
<parameter>string</parameter> exceeds the filesystem's block size, on some
platforms, and as long as the file is on a local filesystem). That is,
there is no need to <function>flock</function> a resource before calling
<function>fwrite</function>; all of the data will be written without
interruption.
