Additional Information

For information about IoWriteErrorLogEntry, see the Windows Driver Kit (WDK) documentation.

Remarks

This command displays information about any pending events in the I/O system's error log. These are events queued by calls to the IoWriteErrorLogEntry function, to be written to the system's event log for subsequent viewing by the Event Viewer.

Only entries that were queued by IoWriteErrorLogEntry but have not been committed to the error log will be displayed.

This command can be used as a diagnostic aid after a system crash because it reveals pending error information that was unable to be committed to the error log before the system halted.
