Gli oggetti globali std::clog e std::wclog uscita di controllo ad un buffer del flusso di attuazione tipo definito (derivato da std::streambuf), associata allo standard stderr flusso di uscita C, ma, a differenza std::cerr / std::wcerr, questi flussi non vengono automaticamente cancellate automaticamente e non legare ( ) 'd con cout.

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.

Questi oggetti sono garantiti per essere costruito prima del primo costruttore di un oggetto statico viene chiamato e sono garantiti per sopravvivere distruttore ultimo di un oggetto statico, in modo che sia sempre possibile scrivere std::clog nel codice utente.

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.

A meno che sync_with_stdio(false) è stato rilasciato, è sicuro per accedere a questi oggetti contemporaneamente da più thread sia per l'output formattato e non formattati.

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.

Esempio

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

Output:

static constructor main function static destructor
