Detailed Description
Member Enumeration Documentation
◆ EStatus
Async.
device status, describes if interface is in Ok condition to continue processing Some interface implementations can support async. execution, and stay "not ready" until background logic finishes (successfully or not)
| Enumerator | |
|---|---|
| eReady | Volume is ready. |
| eFailed | Last operation failed and interface cannot recover. |
| eNoMoreData | Interface reached the end (EOF) |
| eNotReady | Last request did not finish yet. |
