◆ BLI_MEMARENA_STD_BUFSIZE

#define BLI_MEMARENA_STD_BUFSIZE MEM_SIZE_OPTIMAL(1 << 14)

A reasonable standard buffer size, big enough to not cause much internal fragmentation, small enough not to waste resources

◆ BLI_memarena_merge()

void BLI_memarena_merge	(	MemArena *	ma_dst,
		MemArena *	ma_src )

Transfer ownership of allocated blocks from ma_src into ma_dst, cleaning the contents of ma_src.

Note: Useful for multi-threaded tasks that need a thread-local MemArena that is kept after the multi-threaded operation is completed.; Avoid accumulating memory pools where possible as any unused memory in ma_src is wasted every merge.
