* @defgroup s27_2_iosfwd I/O Forward Declarations
|
|
*
|
|
* Nearly all of the I/O classes are parameterized on the type of
|
|
* characters they read and write. (The major exception is ios_base at
|
|
* the top of the hierarchy.) This is a change from pre-Standard
|
|
* streams, which were not templates.
|
|
*
|
|
* For ease of use and compatibility, all of the basic_* I/O-related
|
|
* classes are given typedef names for both of the builtin character
|
|
* widths (wide and narrow). The typedefs are the same as the
|
|
* pre-Standard names, for example:
|
|
*
|
|
* @code
|
|
* typedef basic_ifstream<char> ifstream;
|
|
* @endcode
|
|
*
|
|
* Because properly forward-declaring these classes can be difficult, you
|
|
* should not do it yourself. Instead, include the <iosfwd>
|
|
* header, which contains only declarations of all the I/O classes as
|
|
* well as the typedefs. Trying to forward-declare the typedefs
|
|
* themselves (e.g., "class ostream;") is not valid ISO C++.
|
|
*
|
|
* For more specific declarations, see
|
|
* http://gcc.gnu.org/onlinedocs/libstdc++/27_io/howto.html#10
