Detailed Description
sip_request: The data grabbed from the UDP socket
* Incoming messages: we first store the data from the socket in data[], * adding a trailing \0 to make string parsing routines happy. * Then call parse_request() and req.method = find_sip_method(); * to initialize the other fields. The \r\n at the end of each line is * replaced by \0, so that data[] is not a conforming SIP message anymore. * After this processing, rlPart1 is set to non-NULL to remember * that we can run get_header() on this kind of packet. * * parse_request() splits the first line as follows: * Requests have in the first line method uri SIP/2.0 * rlPart1 = method; rlPart2 = uri; * Responses have in the first line SIP/2.0 NNN description * rlPart1 = SIP/2.0; rlPart2 = NNN + description; * * For outgoing packets, we initialize the fields with init_req() or init_resp() * (which fills the first line to "METHOD uri SIP/2.0" or "SIP/2.0 code text"), * and then fill the rest with add_header() and add_line(). * The \r\n at the end of the line are still there, so the get_header() * and similar functions don't work on these packets. *
