Values
| Name | Description |
|---|---|
| AIOP_PRIORITY_MASK | |
| AIOP_FLAG_PRECACHE | Flags - combine with priorities if needed. |
| AIOP_FLAG_DONTCACHE | |
| AIOP_FLAG_HW_TARGET_MEMORY | Use it to specify memory where read from cpu can be slow. |
| AIOP_MIN | Priorities. |
| AIOP_Low | |
| AIOP_BelowNormal | |
| AIOP_Normal | |
| AIOP_High | |
| AIOP_CriticalPath | |
| AIOP_MAX | |
| AIOP_NUM | |
| AIOP_Precache | Legacy (for back-compat). Better to specify priority and AIOP_FLAG_PRECACHE separately. |
Remarks
Enum for async IO priorities.
