Detailed Description
Memory Alignment services.
Memory alignment support macros | |
| #define | MEM_ALIGN_MASK(a) |
| Alignment mask constant. | |
| #define | MEM_ALIGN_PREV(p, a) |
| Aligns to the previous aligned memory address. | |
| #define | MEM_ALIGN_NEXT(p, a) |
| Aligns to the next aligned memory address. | |
| #define | MEM_IS_ALIGNED(p, a) |
| Returns whatever a pointer or memory size is aligned. | |
| #define | MEM_IS_VALID_ALIGNMENT(a) |
| Returns whatever a constant is a valid alignment. | |
