BLI_memblock_clear()

void BLI_memblock_clear	(	BLI_memblock *	mblk,

Reset elem count to 0 but keep as much memory allocated needed for at least the previous elem count.

BLI_memblock_elem_get()

void * BLI_memblock_elem_get	(	BLI_memblock *	mblk,
		int	chunk,
		int	elem )

Direct access. elem is element index inside the chosen chunk. Double usage: You can set chunk to 0 and set the absolute elem index. The correct chunk will be retrieve.
