( ﾉ╹◡◡╹)ﾉ HRESULT の値から対応するメッセージを取得したいよなーー、俺もな～～～～～

hr2message.cpp

#include <iostream>
#include <stdexcept>
#include <windows.h>

std::string hresult_to_string( HRESULT hr ) {
    constexpr size_t MESSAGE_BUFFER_SIZE          = 1024;
    CHAR             message[MESSAGE_BUFFER_SIZE] = {};

    DWORD            got = FormatMessageA( FORMAT_MESSAGE_FROM_SYSTEM | FORMAT_MESSAGE_IGNORE_INSERTS,
                                nullptr,
                                hr,
                                MAKELANGID( LANG_NEUTRAL, SUBLANG_DEFAULT ),
                                message,
                                MESSAGE_BUFFER_SIZE,
                                nullptr );

    return { message };
}

int main() {
    std::cout << hresult_to_string( E_ACCESSDENIED ) << std::endl;

    return EXIT_SUCCESS;
}
