wenn die Codierung dieses codecvt Facette vertreten ist state-abhängig und state stellt eine Umwandlung Staat, der nicht der ursprüngliche Schaltzustand, schreibt die Zeichen notwendig, um zum ursprünglichen Schaltzustand zurück. Die Charaktere sind zu einem Zeichen-Array, dessen erstes Element wird durch to wies geschrieben. Nicht mehr als to_end-to Zeichen geschrieben werden. Der Parameter to_next wird aktualisiert, um ein nach dem letzten Zeichen geschrieben zeigen .

Original:

if the encoding represented by this codecvt facet is state-dependent, and state represents a conversion state that is not the initial shift state, writes the characters necessary to return to the initial shift state. The characters are written to a character array whose first element is pointed to by to. No more than to_end-to characters are written. The parameter to_next is updated to point one past the last character written.
