<para>
<function>lob->flush</function> actually writes data to the server.
By default, resources are not freed, but using flag
<constant>OCI_LOB_BUFFER_FREE</constant> you can do it explicitly.
Be sure you know what you're doing - next read/write operation to the
same part of LOB will involve a round-trip to the server and initialize
new buffer resources. Tt is recommended to use
<constant>OCI_LOB_BUFFER_FREE</constant> flag only when you are not going
to work with the LOB anymore.
</para>
<para>
<function>lob->flush</function> returns &false; if buffering was not
enabled or an error occurred.
</para>
<para>
&return.success;
