Глобальные объекты std::clog и std::wclog выход управления в поток буфера реализации определенного типа (производное от std::streambuf), связанные со стандартным stderr выходной поток C, но, в отличие от std::cerr / std::wcerr, эти потоки автоматически не покраснел и не автоматически привязать ( ) 'D с соиЬ.

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.

Эти объекты гарантированно будут построены до первого конструктора статического объекта вызывается и они гарантированно пережить последний деструктор статического объекта, так что всегда можно написать std::clog в пользовательском коде.

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.

Если sync_with_stdio(false) было выдано, что это безопасно для одновременного доступа к этим объектам из нескольких потоков для форматированных и неформатированных выход.

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.

Пример

#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";
}

Вывод:

static constructor
main function
static destructor
