Hi,
I am new to FreeBSD kernel programming.
Currently I am trying to work on mbuf data manupulation.

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?
I may be wrong on this one, but according to my understanding, a
m_pullup() followed by a mtod() should do the trick.
depends what he wants to do..
check /sys/sys/mbuf.h and
/sys/kern/uipc_mbuf.c
for all sorts of methods for handling mbufs.
thanks in advance :)
