In the standard library, no. However, a quick google search for "safe c string library" turns up several potentially useful results. Without knowing more about the task you are trying to perform, I cannot recommend any particular third-party implementation.

If this is the only "safe" function that you need beyond the standard functions, then it may be best to roll your own rather than expend the effort of integrating a third-party library, provided you are confident that you can do so without introducing additional bugs.
