Sane non-blocking implementations pretty much have to enable 'partial
writes' and 'enable moving write buffer'. Otherwise the semantics become
insane, as you pointed out.

PARTIAL_WRITES has no effect on the meaning of the return value. It just
controls whether or not the internal write logic tries to continue writing
if the underlying write partially completes

I guess that is clear enough.

SSL_write(ssl, buffe

Call SSL_write with the same parameters until it succeeds. You need
to handle WANT_READ and WANT_WRITE return values.
