sprintf_s was not declared in this scope

Question

I have a C program that uses sprintf_s. It works fine in Windows, but when I compile my code in Linux it gives this error:

sprintf_s was not dec         


        

Answer 1

snprintf is insecure, only sprintf_s is secure. snprintf does not guarantee to add a final \0, leading to possible subsequent overflows. look at https://github.com/rurban/safeclib for a proper implementation.
