Remarks

This event fires after all locked byte ranges in the file specified by FileName are unlocked.

Applications only need to handle this event if they've added a standard filter rule that includes the FS_CE_AFTER_LOCK_CONTROL flag.

The Status parameter contains an NT status code that indicates the outcome of the operation; 0 indicates success. To convert this value to a Win32 error code, call the nt_status_to_win_32_error method. Please note that this event won't fire for failed requests unless the process_failed_requests property is enabled. Applications may change this parameter's value if they want a different NT status code to be returned.

The FileContext and HandleContext parameters are placeholders for application-defined data associated with the file and specific handle, respectively. Please refer to the Contexts topic for more information.

The ResultCode parameter will always be 0 when the event is fired. If the event cannot be handled in a "successful" manner for some reason (e.g., a resource isn't available, security checks failed, etc.), set it to a non-zero value to report an appropriate error. Please refer to the Error Reporting and Handling topic for more information.

This event is fired synchronously; please refer to the Event Types topic for more information.
