sip_branchid(3SIP) Session Initiation Protocol Library Functions sip_branchid(3SIP)NAME
sip_branchid - generate a RFC 3261 complaint branch ID
SYNOPSIS
cc [ flag ... ] file ... -lsip [ library ... ]
#include <sip.h>
char *sip_branchid(sip_msg_t sip_msg);
DESCRIPTION
The sip_branchid() function can be used to generate a value for the branch parameter for a VIA header. The returned string is prefixed with
z9hG4bK to conform to RFC 3261. If sip_msg is null or sip_msg does not have a VIA header, a random value is generated. Otherwise, the value
is generated using the MD5 hash of the VIA, FROM, CALL-ID, CSEQ headers and the URI from the request line. The caller is responsible for
freeing the returned string.
RETURN VALUES
The sip_branchid() function returns a string on success and NULL on failure.
The value of errno is not changed by these calls in the event of an error.

sip_msg_to_str(3SIP) Session Initiation Protocol Library Functions sip_msg_to_str(3SIP)NAME
sip_msg_to_str, sip_hdr_to_str, sip_reqline_to_str, sip_respline_to_str, sip_sent_by_to_str - return string representations
SYNOPSIS
cc [ flag ... ] file ... -lsip [ library ... ]
#include <sip.h>
char *sip_msg_to_str(sip_msg_t sip_msg,
int *error);
char *sip_hdr_to_str(sip_header_t sip_header,
int *error);
char *sip_reqline_to_str(sip_msg_t sip_msg,
int *error);
char *sip_respline_to_str(sip_msg_t sip_msg,
int *error);
char *sip_sent_by_to_str(int *error);
DESCRIPTION
The sip_msg_to_str() function returns the string representation of the SIP message sip_msg. Deleted headers are not included in the
returned string. The caller is responsible for freeing the returned string.
The sip_hdr_to_str() function returns the string representation of the SIP header sip_header. The caller is responsible for freeing the
returned string.
The sip_reqline_to_str() function returns the string representation of the request line from the SIP message sip_msg. The caller is respon-
sible for freeing the returned string.
The sip_respline_to_str() function returns the string representation of the response line from the SIP message sip_msg. The caller is
responsible for freeing the returned string.
The sip_sent_by_to_str() function can be used to retrieve the list of sent-by values registered with the stack. The returned string is a
comma separated list of sent-by values. The caller is responsible for freeing the returned string.
RETURN VALUES
The sip_msg_to_str(), sip_hdr_to_str(), sip_reqline_to_str(), sip_respline_to_str(), and sip_sent_by_to_str() functions return the relevant
string on success and NULL on failure.
The value of errno is not changed by these calls in the event of an error.
ERRORS
For the sip_msg_to_str(), sip_hdr_to_str(), sip_reqline_to_str(), and sip_respline_to_str(), one of the following values is set if the
error is non-null:
EINVAL Input is null.
ENOMEM Memory allocation failure.
On success, the value of the location pointed to by error is set to 0.
