[lwip-users] select timeout

[Mathias Zenger]

Hi,

I have a little problem with select() (socket API, lwIP 1.3.0). I would like
to block for a maximum time of 5 seconds, waiting for incoming data.
Therefor I set up the following structure:

struct timeval socket_to;
socket_to.tv_sec = 5;
socket_to.tv_usec = 0;


Calling select():
...
ret = select(FD_SETSIZE, &fd, NULL, NULL, &socket_to);
...


My problem is that select() does only return if any data was received. The
timeout seems to be ignored. Is there a known issue or am I handling the
select timeout wrong? (By the way: blocking infinite with timeout parameter
== NULL works as expected).

Thanks for your help!
