Re: [lwip-users] Multi threaded TCP model

[Pîrvu Mihai]

The port I'm using is using 1.3.2 version, so I doubt there's this option from the unreleased branch. I'll try to follow how select is implemented and see if there's a non-blocking way to check if a packet has arived on a socket/session so I don't block the thread indefinitely.

I've read that different threads cannot call the same socket/netconn session at the same time, so I guess this is where my problem lays.

You can use the fairly new option LWIP_NETCONN_FULLDUPLEX set to 1, which in combination with thread-local semaphores (LWIP_NETCONN_SEM_PER_THREAD==1) to write from one thread while writing from a 2nd thread. Thread-local semaphores might not be easy to implement, though, depending on your port.
