Re: [lwip-users] packet order with tcp_recv

[Noam weissman]

Hi,

In TCP there should not be such an issue. Packets will be received in
the order they were sent.

TCP is a stream.

BR,
Noam.

Subject: [lwip-users] packet order with tcp_recv

Hi all,

I have a basic question about tcp_recv:

Let's say I have some MBs of data I send to the lwip stack. If (for
whatever reason) tcp packets arrive out of order, will the stack sort
this out for me and call the tcp_recv callback with packets sorted in
correct order? Or do I have to check the sequence number myself to make
sure I put data back together in correct order?

Thanks for your help
Simon
