Re: How to set a socket to non-blocking?


Try

    /* Set the socket for non-blocking mode. */
    int yes = 1;
    if (ioctl(fd, FIONBIO, &yes) < 0)
    {
        /* Error */
    }

The eCos reference talks about how sockets behave when their marked as
non-blocking.  How does one set a socket to non-blocking?
The following fails with an "unsupported" error:

fcntl(fd, F_SETFL, fcntl(fd, F_GETFL) | O_NONBLOCK);
