| Contains flags for handling neighbors of this buddy block. More... | |
Contains the only the flag information about the memory block.
Used to keep track of a block of memory and its status.
Almost the same as MemMngrHead, but stripped of the pointers. Thus the two structs are interchangeable regarding the use of their flags.
| memBlckhead::additionalFlags |
Contains flags for handling neighbors of this buddy block.
| BIT | Name | Purpose |
|---|---|---|
| 0 | IsBlckBeg | Indicates that the block is at the beginning of a BIGGEST_BLCK buddy |
| 1 | IsBlckLast | Indicates that the block is the last block in the list |
| 2 | PRV 4 B | Indicates the size of the adjacent previous block |
| 3 | PRV 8 B | Indicates the size of the adjacent previous block |
| 4 | PRV 16 B | Indicates the size of the adjacent previous block |

| 9 | PRV 512 B | Indicates the size of the adjacent previous block |
| 10 | PRV 1024 B | Indicates the size of the adjacent previous block |
| 11 | PRV 2048 B | Indicates the size of the adjacent previous block |
