sip_add_header(3SIP)				   Session Initiation Protocol Library Functions			      sip_add_header(3SIP)

NAME

       sip_add_header - add a SIP header to the SIP message

SYNOPSIS

       cc [ flag ... ] file ... -lsip [ library ... ]
       #include <sip.h>

       int sip_add_header(sip_msg_t sip_msg, char *header_string);

DESCRIPTION

       The sip_add_header() function takes the SIP header header_string, adds a CRLF (carriage return/line feed) and appends it to the SIP message
       sip_msg. The sip_add_header() function is typically used when adding a SIP header with multiple values.

RETURN VALUES

       The sip_add_header() function returns 0 on success and the appropriate error value on failure.

ERRORS

       On failure, the sip_add_header() function can return one of the following error values:

       EINVAL	 Mandatory parameters are not provided, i.e. null.

       EPERM	 The message cannot be modified.

       ENOMEM	 Error allocating memory for creating headers/parameters.

NAME

       sip_add_branchid_to_via - add a branch parameter to the topmost VIA header in the SIP message

SYNOPSIS

       cc [ flag ... ] file ... -lsip [ library ... ]
       #include <sip.h>

       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 message does not have a VIA header.

       EPERM	 The message cannot be modified.

       ENOMEM	 There is an error allocating memory for creating headers/parameters.
