`template< class State > class fpos;`

Spezialisierungen der Klassen-Template std::fpos identifizieren absoluten Positionen in einem Strom oder in einer Datei. Jedes Objekt vom Typ fpos hält die Byteposition in dem Strom (typischerweise als private Element vom Typ std::streamoff) und den aktuellen Schaltzustand ein Wert vom Typ State (typischerweise std::mbstate_t) .

Original:

Specializations of the class template std::fpos identify absolute positions in a stream or in a file. Each object of type fpos holds the byte position in the stream (typically as a private member of type std::streamoff) and the current shift state, a value of type State (typically std::mbstate_t).
