<H1>ExtParse: Module to get unparsed stream from libwww</H1>

</PRE>

This version of the stream object is a hook for clients that want an
unparsed stream from libwww. The HTExtParse_put_* and HTExtParse_write
routines copy the content of the incoming buffer into a buffer that is
realloced whenever necessary. This buffer is handed over to the client
in HTExtParse_free. See also <A HREF="HTFWrite.html">HTFWriter</A>
for writing to C files.<P>

<H3>Bugs:</H3>

<UL>
<LI>strings written must be less than buffer size.
</UL>

This module is implemented by <A HREF="HTXParse.c">HTXParse.c</A>,
and it is a part of the <A
HREF="http://info.cern.ch/hypertext/WWW/Library/User/Guide/Guide.html">
Library of Common Code</A>.
