>             Project: Qpid Proton
>          Issue Type: Bug
>          Components: proton-c
>    Affects Versions: 0.17.0
>            Reporter: Ken Giusti
>            Assignee: Ken Giusti
>             Fix For: 0.18.0
> the pn_ssl_get_password/cipher_name method takes a target buffer and length and if the
name is known it is copied to the buffer (null terminated) and true is returned.
> However if the name is not known (not yet present) the method returns false and leaves
the buffer untouched.
> This is fine for correctly behaving C programs, but the swig generated code always assumes
the output buffer contains a properly terminated string whether or not the return value is
true.   The swigged code unconditionally calls strlen() on the returned buffer.
