[edit] Parameters

mask - bitmask of the flags to set

[edit] Return value

An object of unspecified type such that

  • if out is an object of type std::basic_ostream<CharT, Traits>, the expression out << setiosflags(mask)
    • has type std::basic_ostream<CharT, Traits>&
    • has value out
    • behaves as if it called f(out, mask)
  • if in is an object of type std::basic_istream<CharT, Traits>, the expression in >> setiosflags(mask)
    • has type std::basic_istream<CharT, Traits>&
    • has value in
    • behaves as if it called f(in, mask)

where the function f is defined as: 

void f(std::ios_base& str, std::ios_base::fmtflags mask)
{
    // set specified flags
    str.setf(mask);
}
