Hi, I am new to FreeBSD kernel programming. Currently I am trying to work on mbuf data manupulation. >From my understanding: data (payload) is stored into one or more mufs which are chained together through m_next pointer. Now, I need to retrive all data in mbuf chain ( mbufs linked by m_next). I am working ip_output() in netinet/ip_output.c Does there exist inbuilt function/macro to retrive all the data in mbuf chain? thanks in advance :)
