Verwendet die Zuweisung a um n*sizeof(Alloc::value_type) Bytes initialisierten Speicher mit der Erinnerung Ortschaft Hinweis hint zuzuweisen. Ruft a.allocate(n, hint) wenn möglich. Falls dies nicht möglich (zB hat keine zwei Argumenten Member-Funktion allocate ()), ruft a.allocate(n)
Original:
Uses the allocator a to allocate n*sizeof(Alloc::value_type) bytes of uninitialized storage with the memory locality hint hint. Calls a.allocate(n, hint) if possible. If not possible (e.g. a has no two-argument member function allocate()), calls a.allocate(n)
