sip_branchid - generate a RFC 3261 complaint branch ID
cc [ flag ... ] file ... -lsip [ library ... ] #include <sip.h> char *sip_branchid(sip_msg_t sip_msg);
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.
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.
