This is correct. It is an error to call MCLFREE if there is a free function (m_ext.ext_free) set. The calling convention could be a lot better (I'd like to have it take a pointer to the mbuf rather than the buffer pointer and size parameters).... > I think either a increment/decrement flag is needed to m_ext.ext_ref, or an > additional decrement function is needed Nope, that function is m_ext.ext_free. -GAWollman -- Garrett A.
