__gnu_cxx::balloc(3)

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 }
