 SIP_ADD_REQUEST_LINE 3SIP "Jan 25, 2007"
 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.
