template< class CharT > /*unspecified*/ get_time( std::tm* tmb, const CharT* fmt);		(seit C++11)

Wenn in einem Ausdruck in >> get_time(tmb, fmt) verwendet, analysiert die Eingabe von Zeichen als ein Datum / Zeit-Wert je nach Format String fmt nach dem std::time_get Facette der locale derzeit in den Ausgabe-Stream out durchdrungen. Der sich ergebende Wert wird in einer std::tm Objekts, auf den durch tmb gespeichert .

Original:

When used in an expression in >> get_time(tmb, fmt), parses the character input as a date/time value according to format string fmt according to the std::time_get facet of the locale currently imbued in the output stream out. The resultant value is stored in a std::tm object pointed to by tmb.

fmt	-	Zeiger auf einen null-terminierten Größentabelle Zeichenfolge, die den Konvertierungsformat Der Format-String besteht aus null oder mehr Umsatz Planer, Leerzeichen und gewöhnliche Zeichen (außer %). Jedes ordentliche Charakter wird erwartet, dass ein Zeichen in der Eingabe-Stream in Groß-und Kleinschreibung Vergleich entsprechen. Jedes Leerzeichen entspricht beliebigen Leerzeichen in der Eingabezeichenfolge. Jede Konvertierung Spezifikation beginnt mit % Charakter, gegebenenfalls gefolgt von E oder O Modifier (ignoriert, wenn nicht durch die locale), gefolgt von dem Zeichen, die das Verhalten der Planer bestimmt. Die Formatangaben entsprechen den POSIX-Funktion strptime(): Original: The format string consists of zero or more conversion specifiers, whitespace characters, and ordinary characters (except %). Each ordinary character is expected to match one character in the input stream in case-insensitive comparison. Each whitespace character matches arbitrary whitespace in the input string. Each conversion specification begins with % character, optionally followed by E or O modifier (ignored if unsupported by the locale), followed by the character that determines the behavior of the specifier. The format specifiers match the POSIX function strptime(): The text has been machine-translated via Google Translate. You can help to correct and verify the translation. Click here for instructions. Conversion specifier Explanation Writes to fields % matches a literal %. The full conversion specification must be %%. (none) t matches any whitespace. (none) n matches any whitespace.
