NAME

       sip_add_request_line, sip_add_response_line - add a request/response line to a SIP message

SYNOPSIS

       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);

DESCRIPTION

       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:
	 INVITE
	 ACK
	 OPTIONS
	 BYE
	 CANCEL
	 REGISTER
	 REFER
	 SUBSCRIBE
	 NOTIFY
	 PRACK
	 INFO

       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".

RETURN VALUES

       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.

ERRORS

       On failure, the sip_add_response_line() and sip_add_request_line() functions could return one of the following errors:

       EINVAL	  If mandatory input is not provided or if the input is invalid.

       ENOTSUP	  If the input SIP message cannot be modified.

       ENOMEM	  If memory allocation fails when creating the request/response line or when creating headers in the ACK request.
