Follow-up Comment #1, bug #27116 (project lwip):
Hi,
select with timeout 0 perfectly works for me on BF536.
You should upgrade to Visual DSP++ 5.0 Update 6, it has a more recent version
of LwIP:

int ReadTimeOut(int sock, int tv_ms)
{
// Set up FD set and timeval
fd_set efds;
FD_ZERO(&efds);
FD_SET(sock, &efds);
struct timeval tv;
tv.tv_sec = tv_ms/1000;
tv.tv_usec = 1000*(tv_ms%1000);
// Wait socket for specified timeout
return select(sock+1, &efds, NULL, NULL, &tv);
}
