The websUrlParse procedure cracks the URL into its constituent components. To 
store the parts, websUrlParse allocates a dynamic buffer. This must eventually 
be freed via <A href="../basicapi/bfree.htm">bfree</A> by the caller.</P><P>websUrlParse 
stores pointers to the URL components in <EM>host, path, port, query, proto, tag 
</EM>and <EM>ext. </EM>If any of these parameters contains NULL, that component 
is ignored.</P><P> <B>Note:</B> Tag parsing is not fully supported.</P><h2>Return 
Value</h2><p> Returns 0 if successful. Returns -1 if memory cannot be allocated 
to hold the results.</p><h2>Example</h2><pre> char_t *host, *port, *buf; 
websUrlParse(url, &amp;buf, &amp;host, NULL, &amp;port, NULL, NULL, NULL, NULL); </pre><h2>Stability 
Classification</h2><p>Stable.</p><h2>See Also</h2><p> <A href="../basicapi/balloc.htm">balloc</A>,
