No, this is pure C++ (non-managed) thing. It is used strictly in read-only places. It makes absolutely no sense to use things like std::string (and allocate it each time) when you need to pass string or fragment of string or array to consumers. For write-only access I also have target<T> that safely wraps all memcpy, memmove, strcpy[_s] cases.
