RE : [lwip-users] Problem with sockets layer

[Frédéric BERNON]

Sorry for you, but Simon, who have study the select code, is now in holidays, and I'm not sure that lot of developers know the current implementation.

 

But some questions:

 

1/ which lwIP release do you use?

 

2/ want kind of client/server or application do you try to do? Because, in your previous email, you wrote "The fact is that I am trying to make a standard code work. In it there is a tcpserver which does create a socket, bind it, listen and when accept is done send. On the other hand I´ve got a tcpclient which does create a socket, connect to the server and receive." and if I understand, you have try select as a workaround, right? Because I think that perhaps the solution is to fix the inital problem, no?

Objet : [lwip-users] Problem with sockets layer

Hello to everybody,

I am  working with the sockets layer on a lwip stack with a port to Nucleus RTOS. A few days ago I asked a question dealing with the select function and semaphores. Further investigations have led me to discover that the select function gives up waiting for the timeval structure when I use connect previously. This sounds pretty strange, but now I am sure about that. In the same piece of code I have written a menu with 2 options. In the first one I use select after listen, and it waits the introduced value (5 seconds), all ok. But when I choose the second option, another socket is used with connect, and in the next select call I can see through debugging that no waiting takes place (the same value is used, 5 seconds). Has somebody experienced any similar problem???  Am I making any obvious mistake???

Thanks a lot for your useful help.
