Ends an asynchronous reserve and append operation. This method cannot be inherited.
public:
virtual System::IO::Log::SequenceNumber EndReserveAndAppend(IAsyncResult ^ result);public System.IO.Log.SequenceNumber EndReserveAndAppend (IAsyncResult result);abstract member EndReserveAndAppend : IAsyncResult -> System.IO.Log.SequenceNumber
override this.EndReserveAndAppend : IAsyncResult -> System.IO.Log.SequenceNumberPublic Function EndReserveAndAppend (result As IAsyncResult) As SequenceNumberParameters
- result
- IAsyncResult
A reference to the outstanding asynchronous I/O request.
Returns
The sequence number of the appended log record.
Implements
Exceptions
result is invalid.
End has already been called for this asynchronous operation.
The request cannot be performed because of an unexpected I/O exception.
The method was called after the sequence has been disposed of.
There is not enough memory to continue the execution of the program.
Remarks
This method blocks until the I/O operation has completed. Errors that occur during an asynchronous write request, such as a disk failure during the I/O request, become visible when EndReserveAndAppend is called.
This method must be called exactly once on every IAsyncResult returned by the BeginReserveAndAppend method.
