Thanks for your help, I posted the sample (which I guess is a little misleading given that it's taken straight off the OpenSSL page I noted) and not what it currently does which is very close to what you've suggested.  So that's one problem I don't have to worry about!  Thanks again  ... N

No, because is error is reported separately, and you're not setting "ok = 1" for the other errors.

Each error is reported separately.

Yes, though I don't think of it as "ORing".
