| Typedefs |
| ios |
Supports the ios class from the old iostream library. |
| streamoff |
Supports internal operations. |
| streampos |
Holds the current position of the buffer pointer or file pointer. |
| streamsize |
Specifies the size of the stream. |
| wios |
Supports the wios class from the old iostream library. |
| wstreampos |
Holds the current position of the buffer pointer or file pointer. |
| Manipulators |
| boolalpha |
Specifies that variables of type bool appear as true or false in the stream. |
| dec |
Specifies that integer variables appear in base 10 notation. |
| fixed |
Specifies that a floating-point number is displayed in fixed-decimal notation. |
| hex |
Specifies that integer variables appear in base 16 notation. |
| internal |
Causes a number's sign to be left justified and the number to be right justified. |
| left |
Causes text that is not as wide as the output width to appear in the stream flush with the left margin. |
| noboolalpha |
Specifies that variables of type bool appear as 1 or 0 in the stream. |
| noshowbase |
Turns off indicating the notational base in which a number is displayed. |
| noshowpoint |
Displays only the whole-number part of floating-point numbers whose fractional part is zero. |
| noshowpos |
Causes positive numbers to not be explicitly signed. |
| noskipws |
Cause spaces to be read by the input stream. |
| nounitbuf |
Causes output to be buffered and processed when the buffer is full. |
| nouppercase |
Specifies that hexadecimal digits and the exponent in scientific notation appear in lowercase. |
| oct |
Specifies that integer variables appear in base 8 notation. |
| right |
Causes text that is not as wide as the output width to appear in the stream flush with the right margin. |
| scientific |
Causes floating point numbers to be displayed using scientific notation. |
| showbase |
Indicates the notational base in which a number is displayed. |
| showpoint |
Displays the whole-number part of a floating-point number and digits to the right of the decimal point even when the fractional part is zero. |
| showpos |
Causes positive numbers to be explicitly signed. |
| skipws |
Cause spaces to not be read by the input stream. |
| unitbuf |
Causes output to be processed when the buffer is not empty. |
| uppercase |
Specifies that hexadecimal digits and the exponent in scientific notation appear in uppercase. |
| Classes |
| basic_ios |
The template class describes the storage and member functions common to both input streams (of template class basic_istream) and output streams (of template class basic_ostream) that depend on the template parameters. |
| fpos |
The template class describes an object that can store all the information needed to restore an arbitrary file-position indicator within any stream. |
| ios_base |
The class describes the storage and member functions common to both input and output streams that do not depend on the template parameters. |
