I am trying to combine std::left and std::setw() as a single

function. The following code ignores the "left" manipulator. What am I

doing wrong? TIA



struct leftsetw // combined functions (left/width)

{

leftsetw(int w) : width(w) {}

int width;

};

ostream &operator<<(ostream &o, const leftsetw &a)

{

o.left, o.width(a.width);

return o;

}



ostringstream oss;

oss.str(""); oss << "Test " << leftsetw(12) << 42;
