How to achieve strncpy() functionality with strncpy_s() function?

Question

There\'re certain cases when I really need strncpy() funcitonalty - for example I have a function in a predefined interface that is passed an address of the buf

Answer 1

You want null-termination where actualLength < length, and no null-termination where actualLength == length, right?

So use strncpy_s for the case where actualLength < length and memcpy_s where actualLength == length.
