- create a response for a SIP request
cc [ flag ... ] file ... -lsip [ library ... ] #include <sip.h> sip_msg_t sip_create_response(sip_msg_t sip_request, int response_code, char *response_phase, char *totag, char *contact_uri);
The sip_create_response() function creates and returns a SIP message in response to the SIP request sip_request. The response line in the resulting SIP message is created using the response code in response_code and the phrase in response_phrase. The response line has the SIP-Version of “2.0”. If a non-null totag is specified, the resulting SIP response has a TO header with a tag value from totag. If totag is null and the response_code is anything other than 100 (TRYING), sip_create_response() adds a TO header with a randomly generated tag value. If the response_code is 100 and totag is null, the SIP response has a TO header without a tag parameter. If contact_uri is non-null, a CONTACT header is added to the SIP response with the URI specified in contact_uri. The SIP response has the following headers copied from sip_request:
The sip_create_response() function returns the resulting SIP message on success and NULL on failure.
The value of errno is not changed by these calls in the event of an error.
