- add a request/response line to a SIP message
cc [ flag ... ] file ... -lsip [ library ... ] #include <sip.h> int sip_add_request_line(sip_msg_t sip_request, sip_method_t method, char *request_uri);
int sip_add_response_line(sip_msg_t sip_response, int response_code, char *response_phase);
The sip_add_request_line() function adds a request line to the SIP message sip_request. The request line is created using the SIP method specified in method and the URI in request_uri. The SIP method can be one of the following:
The resulting request line has the SIP-Version of “2.0”.
The sip_add_response_line() function adds a response line to the SIP message sip_response. The response line is created using the response code response_code and the phrase in response_phrase. If the response_code is one that is listed in RFC 3261, sip_get_resp_desc() can be used to get the response phase for the response_code. The resulting response line has the SIP-Version of “2.0”.
The sip_add_response_line() and sip_add_request_line() functions return 0 on success and the appropriate error value in case of failure.
The value of errno is not changed by these calls in the event of an error.
On failure, the sip_add_response_line() and sip_add_request_line() functions could return one of the following errors:
If mandatory input is not provided or if the input is invalid.
If the input SIP message cannot be modified.
If memory allocation fails when creating the request/response line or when creating headers in the ACK request.
