cc [ flag ... ] file ... -lsip [ library ... ] #include <sip.h> int sip_add_branchid_to_via(sip_msg_t sip_msg, char *branchid);
The sip_add_branchid_to_via() function adds a branch param to the topmost VIA header in the SIP message sip_msg. Note that a new header is created as a result of adding the branch parameter and the old header is marked deleted. Applications with multiple threads working on the same VIA header need to take note of this.
These functions return 0 on success and the appropriate error value on failure.
On failure, functions that return an error value may return one of the following: EINVAL
Mandatory parameters are not provided or are NULL. For sip_add_branchid_to_via(), the topmost VIA header already has a branch param or the SIP message does not have a VIA header.
The message cannot be modified.
There is an error allocating memory for creating headers/parameters.
