Re: [lwip-users] Socket read/write and threads

[Nicolas Pinault]

Hi Yoav,

Pardon me for barging in... I have encountered the same issue about a
week or two ago.
Using select() would be the natural choice for performing multiple
non-blocking operations.

You can either:
1. Use select() in a single thread to perform both Rx & Tx (recommended)
2. Keep Rx and Tx threads locked and waiting on a select running in
another thread (in essence adding the locking mechanism that lwIP does
not support)
  

I was already thinking of using select but I can't see how to use it in this situation.
Waiting on receive is ok for me. Waiting on transmit is the problem.
Can you provide a small excerpt of code ?

Regards,
Nicolas

HTH,
Yoav.

Is this a threading problem ?
   
        

Yep, using a socket from more than one thread at the same time is
currently not supported.
      

Ok.
So, what do you recommend to asynchronously send and receive data
(with a socket).
