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);
len = SSL_write( ssl,
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?
