Members	Description
INDEX Cnt;	How many elements are used.
INDEX Avail;	How many elements are available in his array.
_32 Lock;	A simple exchange lock on the data for insert and delete. For thread safety.
INDEX Size;	How big each element of the array is.
_8 data[1];	The physical array.

Description

Data Blocks are like LinkBlocks, and store blocks of data in slab format. If the count of elements exceeds available, the structure is grown, to always contain a continuous array of structures of Size size.

Remarks

When blocks are deleted, all subsequent blocks are shifted down in the array. So the free blocks are always at the end.
