char* build_req_buf_from_sip_req ( struct sip_msg * msg,

unsigned int * returned_len,

struct dest_info * send_info

)

builds a request in memory from another sip request.
Side-effects: - it adds lumps to the msg which are _not_ cleaned. All the added lumps are HDR_VIA_T.

it might change send_info->proto and send_info->send_socket if proto fallback is enabled (see below).

Uses also global_req_flags ( OR'ed with msg->msg_flags, see send_info below).

Parameters:

msg - sip message structure, complete with lumps

returned_len - result length (filled in)

send_info - dest_info structure (value/result), contains where the packet will be sent to (it's needed for building a correct via, fill RR lumps a.s.o.). If MTU based protocol fall-back is enabled (see flags below), send_info->proto might be updated with the new protocol. msg->msg_flags used:

FL_TCP_MTU_FB, FL_TLS_MTU_FB and FL_SCTP_MTU_FB - fallback to the corresp. proto if the built message > mtu and send_info->proto==PROTO_UDP. It will also update send_info->proto.
FL_FORCE_RPORT: add rport to via

Returns:
pointer to the new request (pkg_malloc'ed, needs freeing when done) and sets returned_len or 0 on error.
