[lwip-users] recv and sent callbacks usage

[narke]

Hi,

I have a few questions about the raw api:

1. When a connection received 3 segments, how many times the recv
callback will be called?
2. After continuously  did 3 times of tcp_write, how many times the
sent callback will be got called after all the data have been sent out
and acknowledged?  In the sent callback, how do I understand and use
the 'len' argument?

Thanks in advance.
