Question

I’m working with the ZeroMQ library which uses void * to represent blocks of arbitrary binary data. However I’d like to use std::vector to copy and move these blocks around. What is the preferred, idiomatic way to make a std::vector representing raw bytes? I’m currently using a std::vector<unsigned char> but I want to make sure my code makes sense to other people.

Answer 1

Either

std::vector<unsigned char>

or

#include <cstdint>

std::vector<std::uint8_t>

both seem fine to me.
