グローバルオブジェクトの標準C出力ストリームstd::clogに関連付けられている実装定義型（std::wclog由来）のストリームバッファへstd::streambufとstderr制御出力が、std::cerr/std::wcerr、これらのストリームが自動的にフラッシュされていないと自動的に提携されていないとは違って（ COUTで） 'D.

Original:

The global objects std::clog and std::wclog control output to a stream buffer of implementation-defined type (derived from std::streambuf), associated with the standard C output stream stderr, but, unlike std::cerr/std::wcerr, these streams are not automatically flushed and not automatically tie()'d with cout.

これらのオブジェクトは、静的オブジェクトの最初のコンストラクタが呼び出される前に建設されることが保証されて、彼らは、それがユーザーコードでstd::clogに書き込みすることは常に可能であるように、静的オブジェクトの最後のデストラクタよりも長生きすることが保証されています.

Original:

These objects are guaranteed to be constructed before the first constructor of a static object is called and they are guaranteed to outlive the last destructor of a static object, so that it is always possible to write to std::clog in user code.

sync_with_stdio(false)が発行されていない限り、それは同時にフォーマットし、フォーマットされていない出力の両方に複数のスレッドからこれらのオブジェクトにアクセスしても安全です.

Original:

Unless sync_with_stdio(false) has been issued, it is safe to concurrently access these objects from multiple threads for both formatted and unformatted output.

例

#include <iostream>
struct Foo {
    int n;
    Foo() {
       std::clog << "static constructor\n";
    }
    ~Foo() {
       std::clog << "static destructor\n";
    }
};
Foo f; // static object
int main()
{
    std::clog << "main function\n";
}

Output:

static constructor
main function
static destructor
