int sip_add_branchid_to_via(sip_msg_t sip_msg, char *branchid);
DESCRIPTION
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.RETURN VALUES
These functions return 0 on success and the appropriate error value on failure.ERRORS
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 mes-
sage does not have a VIA header. EPERM The message cannot be modified. ENOMEM There is an error allocating memory for creating headers/parameters.ATTRIBUTES
