fmtflags flags() const;

1

Returns: The format control information for both input and output.

fmtflags flags(fmtflags fmtfl);

2

Postcondition: fmtfl == flags().

3

Returns: The previous value of flags().

fmtflags setf(fmtflags fmtfl);

4

Effects: Sets fmtfl in flags().

5

Returns: The previous value of flags().

fmtflags setf(fmtflags fmtfl, fmtflags mask);

6

Effects: Clears mask in flags(), sets fmtfl & mask in flags().

7

Returns: The previous value of flags().

void unsetf(fmtflags mask);

8

Effects: Clears mask in flags().

streamsize precision() const;

9

Returns: The precision to generate on certain output conversions.

streamsize precision(streamsize prec);

10

Postcondition: prec == precision().

11

Returns: The previous value of precision().

streamsize width() const;

12

Returns: The minimum field width (number of characters) to generate on certain output conversions.

streamsize width(streamsize wide);

13

Postcondition: wide == width().
