Duhhh. Of course, a foolish code error, declaring bytesWritten as size_t
rather than int and comparing with 0.
Thanks for your tolerance. I'm regularly amazed by the good humour that you
all show to idiot users.

With all due respect: there must be something wrong with your code.
There is just one place in SSL_get_error(), at which SSL_ERROR_NONE
is returned: in the case "i>0", meaning that the return code was
positive. Are you sure, that your call to SSL_get_error() is correct?

Yes, that is because it cannot happen...
