I am working with the ‘raw’ API to develop an
event driven TCP application. My tcp_recv() callback needs to be
able to process a partial pbuf chain, free the part handled by the callback,
and then save remaining pbufs for later use. So for example if the
chain looks like this: A->B->C->D, I want to process free A
& B and keep C & D. Am I correct in trying to do this by calling pbuf_ref( C )
and then pbuf_free( A )? Where does pbuf_dechain fit in? |
