Hello,
Can anyone please please tell me how to received the messages from the
group as digest instead of individual mails. My mailbox is getting
bombarded with these mails.
Thanks,

SSL_peek() there isn't much documentation about this one.
My situation is this:
* I'm using full non-blocking IO.
* My application's main task in the moment is sending bulk data, a lot
of data (enough to cause flow control bottleneck).
* My application is not interested in reading any more data (yet) so it
doesn't want to call SSL_read() as that might return some data
(destructively) from the buffering.
* But I want to allow OpenSSL to service the connection for the
WANT_READ condition I got back from SSL_write().
So what do I do ?
My program is being told by the operating system I can write(), the
operating system socket send buffers are empty, but OpenSSL is returning
WANT_READ to SSL_write(), so I need to stop calling SSL_write() and wait
for data to arrive. This means temporally ignoring the operating
systems indication I may write data (which was previously driving my
SSL_write() operations). So I'm guessing I can call SSL_peek() to clear
that situation, that function doesn't appear documented but exists and
I'm guessing it will allow the read side to be serviced but not remove
any data (destructively) from buffering. Which is what I need at this
point ?
But I then need to know from SSL_peek() that the problem is now cleared,
so I can try SSL_write() again, but surely it will always return
WANT_READ. Maybe there is another indicator I can use to ask OpenSSL
"Did the read operation I just do, clear the WANT_READ condition I got
to my last SSL_write() function ?". If I get a Yes back, I can then
re-enable my SSL_write() operations driven from operating system socket
is writable event indication.
Your thoughts appreciated,
Darryl
