The beauty and simplicity of the good old C-style void* in C++ 1 month ago
Anything can be aliased by char, unsigned char, std::byte (as well as signed char in C), and usually uint8_t == unsigned char, thus by extension any valid void pointer can be cast to u8*.
Thus void*+size is usually the right type if ones only care for the memory representation of an object (cstring functions like memcpy, etc.)
Most likely one would have both overloads:
void Hexdump(const void *p, size_t size); // (1)
template<typename T> // (2)
inline void Hexdump(const T &obj) {
return Hexdump(&obj, sizeof(T));
}
(1) could also take std::span<const u8>, but (void*, size) is the more common idiom, more convenient to use and to read , as it is unambiguous which overload it is.
