(Uniform Resource Identifier)<p>For each parser (headers, SIP message or URI), you'll always find something close to this minimal subset of methods:<p><pre> // allocation/release of memory. xxxx_init(osip_xxx_t **el); xxxx_free(osip_xxx_t *el);</pre><p><pre> xxxx_parse(osip_xxx_t *el, char *source); xxxx_to_str(osip_xxx_t *el, char **dest);</pre><p><pre></pre><p>For the URI parser, the API is documented in <a class="el" href="osip__uri_8h.html">osip_uri.h</a><p>Here is the sequence needed to parse a given buffer containing a sip URI:<p><pre> osip_uri_t *uri; int i;</pre><p><pre> i=osip_uri_init(&uri); if (i!=0) { fprintf(stderr, "cannot allocate\n"); return -1; } i=osip_uri_parse(uri, buffer); if (i!=0) { fprintf(stderr, "cannot parse uri\n"); } osip_uri_free(uri);</pre><p>Here is the sequence needed to convert the URI into a printable string. Note that in this sequence, dest is allocated dynamically and must be released at the end of the call sequence to avoid memory leaks.<p><pre> char *dest; i = osip_uri_to_str(uri, &dest); if (i!=0) { fprintf(stderr, "cannot get printable URI\n"); return -1; } fprintf(stdout, "URI: %s\n", dest); osip_free(dest);</pre> <hr size="1"><address style="align: right;"><small>Generated on Tue Sep 7 15:08:00 2004 for libosip by<a href="http://www.doxygen.org/index.html"><img src="doxygen.png" alt="doxygen" align="middle" border=0 ></a> 1.3.8 </small></address></body></html>⌨️ 快捷键说明
