fmtflags flags( ) const; 
fmtflags flags(
      fmtflags _Fmtfl
);

Parameters

• _Fmtfl
  The new fmtflags setting.

Return Value

The previous or current fmtflags setting.

Remarks

See the manipulators section for ios for a list of the flags.

The first member function returns the stored format flags. The second member function stores _Fmtfl in the format flags and returns its previous stored value.
