Use picotcp without sockets?

[tbarbette]

Hi all,

Is it possible to use picotcp without sockets. That is, instead of calling picotcp_socket_open, I call a function to which I pass all incoming packets (received using eg. DPDK) and transmit packets by my own means.

Thanks,
Tom

Hello Tom,

in this GPL fork we have added two additional types of sockets for these purposes:

• Raw sockets
• Link layer (packet) sockets

API for RAW IP sockets (compile with RAW=1):
https://github.com/virtualsquare/picotcp/blob/master/modules/pico_ipv4.h#L160

API for PACKET SOCKETS (compile with PACKET_SOCKET=1):
https://github.com/virtualsquare/picotcp/blob/master/modules/pico_socket_ll.h

HTH,

It seems great !

If I get it correctly, the idea is that my application implements the few headers, right?

Would an example be available somewhere?
