As an example, do your safe API do null pointer checks. This is because strcpy, strlen and the like don't, which is one of the reasons why they are considered unsafe. But then, if you guarantee that you are not passing a null pointer to one of these API, why take the hit of the additional checks when you know that these are safe.
Do you really think that comparing a pointer to NULL is going to be a speed hit? I would imagine that on most architectures it boils down to one or two machine code instructions.
