Module: sip-router Branch: master Commit: 7b878801737e7f368a22b1adcc1f2c05b9e8585a URL: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=7b87880… Author: Daniel-Constantin Mierla <miconda(a)gmail.com> Committer: Jan Janak <jan(a)iptel.org> Date: Fri Mar 20 16:42:26 2009 +0100 New functions that can be used to search for a header with given type This patch adds two new functions to the sip-router core. Function get_hdr can be used to find the first occurrence of header with a given type in a sip message if the particular header type does not have its own hook in the sip_msg data structure. The second function next_sibling_hdr can be used to find the next occurence of header with the same type as the header in parameter in the sip message.
