- *
- * The template argument, @a Nb, may be any non-negative number,
- * specifying the number of bits (e.g., "0", "12", "1024*1024").
- *
- * In the general unoptimized case, storage is allocated in word-sized
- * blocks. Let B be the number of bits in a word, then (Nb+(B-1))/B
- * words will be used for storage. B - Nb%B bits are unused. (They are
- * the high-order bits in the highest word.) It is a class invariant
- * that those unused bits are always zero.
- *
- * If you think of %bitset as "a simple array of bits," be aware that
- * your mental picture is reversed: a %bitset behaves the same way as
- * bits in integers do, with the bit at index 0 in the "least significant
- * / right-hand" position, and the bit at index Nb-1 in the "most
- * significant / left-hand" position. Thus, unlike other containers, a
- * %bitset's index "counts from right to left," to put it very loosely.
- *
- * This behavior is preserved when translating to and from strings. For
- * example, the first line of the following program probably prints
- * "b('a') is 0001100001" on a modern ASCII system.
- *
- * @code
- * #include <bitset>
- * #include <iostream>
- * #include <sstream>
- *
- * using namespace std;
- *
- * int main()
- * {
- * long a = 'a';
- * bitset<10> b(a);
- *
- * cout << "b('a') is " << b << endl;
- *
- * ostringstream s;
- * s << b;
- * string str = s.str();
- * cout << "index 3 in the string is " << str[3] << " but\n"
- * << "index 3 in the bitset is " << b[3] << endl;
- * }
- * @endcode
- *
- * Also see http://gcc.gnu.org/onlinedocs/libstdc++/ext/sgiexts.html#ch23
- * for a description of extensions.
- *
- * @if maint
- * Most of the actual code isn't contained in %bitset<> itself, but in the
- * base class _Base_bitset. The base class works with whole words, not with
- * individual bits. This allows us to specialize _Base_bitset for the
- * important special case where the %bitset is only a single word.
- *
- * Extra confusion can result due to the fact that the storage for
- * _Base_bitset @e is a regular array, and is indexed as such. This is
- * carefully encapsulated.

- * @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 &lt;iosfwd&gt;
- * 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

-// From Standard C++ point of view, there are 13 such types:
-// * integers
-// bool (1)
-// char, signed char, unsigned char (3)
-// short, unsigned short (2)
-// int, unsigned (2)
-// long, unsigned long (2)
-//

-// GNU C++ undertstands (where supported by the host C-library)

-//
-// which brings us to 15 fundamental arithmetic data types in GNU C++.

-// Since a numeric_limits<> is a bit tricky to get right, we rely on

- /**
- * @brief The actual work of input and output (interface).
- *
- * This is a base class. Derived stream buffers each control a
- * pair of character sequences: one for input, and one for output.
- *
- * Section [27.5.1] of the standard describes the requirements and
- * behavior of stream buffer classes. That section (three paragraphs)
- * is reproduced here, for simplicity and accuracy.
- *
- * -# Stream buffers can impose various constraints on the sequences
- * they control. Some constraints are:
- * - The controlled input sequence can be not readable.
- * - The controlled output sequence can be not writable.
- * - The controlled sequences can be associated with the contents of
- * other representations for character sequences, such as external
- * files.
- * - The controlled sequences can support operations @e directly to or
- * from associated sequences.
- * - The controlled sequences can impose limitations on how the
- * program can read characters from a sequence, write characters to
- * a sequence, put characters back into an input sequence, or alter
- * the stream position.
- * .
- * -# Each sequence is characterized by three pointers which, if non-null,
- * all point into the same @c charT array object. The array object
- * represents, at any moment, a (sub)sequence of characters from the
- * sequence. Operations performed on a sequence alter the values
- * stored in these pointers, perform reads and writes directly to or
- * from associated sequences, and alter "the stream position" and
- * conversion state as needed to maintain this subsequence relationship.
- * The three pointers are:
- * - the <em>beginning pointer</em>, or lowest element address in the
- * array (called @e xbeg here);
- * - the <em>next pointer</em>, or next element address that is a
- * current candidate for reading or writing (called @e xnext here);
- * - the <em>end pointer</em>, or first element address beyond the
- * end of the array (called @e xend here).
- * .
- * -# The following semantic constraints shall always apply for any set
- * of three pointers for a sequence, using the pointer names given
- * immediately above:
- * - If @e xnext is not a null pointer, then @e xbeg and @e xend shall
- * also be non-null pointers into the same @c charT array, as
- * described above; otherwise, @e xbeg and @e xend shall also be null.
- * - If @e xnext is not a null pointer and @e xnext < @e xend for an
- * output sequence, then a <em>write position</em> is available.
- * In this case, @e *xnext shall be assignable as the next element
- * to write (to put, or to store a character value, into the sequence).
- * - If @e xnext is not a null pointer and @e xbeg < @e xnext for an
- * input sequence, then a <em>putback position</em> is available.
- * In this case, @e xnext[-1] shall have a defined value and is the
- * next (preceding) element to store a character that is put back
- * into the input sequence.
- * - If @e xnext is not a null pointer and @e xnext< @e xend for an
- * input sequence, then a <em>read position</em> is available.
- * In this case, @e *xnext shall have a defined value and is the
- * next element to read (to get, or to obtain a character value,
- * from the sequence).
