NAME

__gnu_cxx::balloc

SYNOPSIS

Classes
    class __mini_vector
        __mini_vector<> is a stripped down version of the full-fledged
        std::vector<>.
    class _Bitmap_counter
        The bitmap counter which acts as the bitmap manipulator, and
        manages the bit-manipulation functions and the searching and
        identification functions on the bit-map.
    class _Ffit_finder
        The class which acts as a predicate for applying the first-fit
        memory allocation policy for the bitmap allocator.
Enumerations
    enum { bits_per_byte, bits_per_block }
Functions
    void __bit_allocate (size_t *__pbmap, size_t __pos)  throw ()
    void __bit_free (size_t *__pbmap, size_t __pos)  throw ()
    template<typename _InputIterator, typename _Predicate> _InputIterator
        __find_if (_InputIterator __first, _InputIterator __last,
        _Predicate __p)
    template<typename _ForwardIterator, typename _Tp, typename _Compare>
        _ForwardIterator __lower_bound (_ForwardIterator __first,
        _ForwardIterator __last, const _Tp &__val, _Compare __comp)
