> what is wrong with NULL? One of the few advantages of ISO standardization is you can just read the associated papers to answer questions like this: https://wg21.link/p2312 https://wg21.link/p2312 The quick bullet points: * Surprises when invoking a type-generic macro with a NULL argument. * Conditional expressions such as (1 ? 0 : NULL) and (1 ? 1 : NULL) have different status depending how NULL is defined * A NULL argument that is passed to a va_arg function that expects a pointer can have severe consequences. On many architectures nowadays int and void* have different size, and so if NULL is just 0, a wrongly sized argument is passed to the function.
