Re: [Boost-users] Boost Regex use of &*string.begin()

Hi

The boost regex library makes liberal use of &*string.begin()

Is this construct safe? Are its semantics specified by the standard?

It isn't specified by the current std: but all current implementations I'm aware of do support it. The next (currently draft) std requires that basic_string's buffer be contiguous, so it will be std-mandated shortly. HTH, John.
