std::clog vs std::cerr

[philip82148]

This is an ADR(Architecture Decision Record) rather than an issue I will consider in the future.
But the discussion about this is open.

The reason I chose std::clog is std::cerr flushes std::cout before outputting.

std::clog

std::cout << "This is temporarily buffered to std::cout.";

int my_int = 15;
std::clog << "[dump] " << my_int << std::endl;

std::cout << "NOW STD::COUT FLUSHED" <<std::endl;

[dump] 15
This is temporarily buffered to std::cout.NOW STD::COUT FLUSHED

std::cerr

std::cout << "This is temporarily buffered to std::cout.";

int my_int = 15;
std::cerr << "[dump] " << my_int << std::endl;

std::cout << "NOW STD::COUT FLUSHED" <<std::endl;

This is temporarily buffered to std::cout.[dump] 15
NOW STD::COUT FLUSHED
