Hi,
I've noticed that SSL_read() will either read from the socket, or
return buffered data, but never both. That is, if there are (eg) 1000
bytes of data waiting to be read, and I call SSL_read() asking for
1500 bytes, it will return only the 1000 buffered bytes, rather than
reading from the socket to supply the other 500.
This means that if I call SSL_read() in a loop like so:
do {
SSL_read(x, ...);
} while(SSL_pending(x));
it will read once from the socket, and then return all of the data
which was fetched; it won't leave data in the buffer, and it won't sit
in the loop for as long as data is arriving from the peer.
Can I rely on this behaviour to stay the same in future OpenSSL
versions?
