◆ alloc_bit_block()

template<class BA, class PA, class APool>

bm::word_t * bm::mem_alloc< BA, PA, APool >::alloc_bit_block ( unsigned alloc_factor = 1 )

inline

Allocates and returns bit block.

Parameters

alloc_factor indicated how many blocks we want to allocate in chunk total allocation is going to be bm::set_block_size * alloc_factor Default allocation factor is 1

Definition at line 351 of file bmalloc.h.

◆ alloc_gap_block()

inline

Allocates GAP block using bit block allocator (BA).

GAP blocks in BM library belong to levels. Each level has a correspondent length described in bm::gap_len_table<>

level	GAP block level.
glevel_len	table of level lengths
