Parametri

mask

-

bitmask of the flags to set

Valore di ritorno

Restituisce un oggetto di tipo non specificato tale che se str è il nome di un flusso di output di tipo std::basic_ostream<CharT, Traits> o std::basic_istream<CharT, Traits>, allora l'espressione str << setiosflags(mask)str >> setiosflags(mask) o si comporta come se il codice riportato di seguito è stato eseguito:

Original:

Returns an object of unspecified type such that if str is the name of an output stream of type std::basic_ostream<CharT, Traits> or std::basic_istream<CharT, Traits>, then the expression str << setiosflags(mask) or str >> setiosflags(mask) behaves as if the following code was executed:
