Issue with select after SSL_get_wfd

[Grace Priscilla Jero <grace.priscilla@xxxxxxxxx>]

Hi All,

I want to know the status of the SSL_WRITE for DTLS on UDP on a non-blocking socket. Only if the other end does the recvfrom I want to continue with subsequent SSL_WRITE.

Below is what I have tried.

//Making the socket blocking - if I dont do below then select call hangs

if (wfd = SSL_get_wfd(ssl))

    {

            flags = fcntl(wfd, F_GETFL);

            flags &= ~O_NONBLOCK;

            fcntl(a_wfd, F_SETFL, flags);

                FD_SET(wfd, &write_fds);

    }

len = SSL_write(          ssl,

                                     buf,

                                     elen);

i = select(wfd+1, NULL, &write_fds, 0, 0);

The other side has not yet done the SSL_read but i is "1".

Is their something wrong with this?

Thanks,

Grace
