  • Article

Wait until the following conditions are satisfied:

  • There are one or more elements in ChangeNotifyEntry.NotifyEventList.

  • This change notification request is the oldest outstanding request on this Open. This means multiple change notification requests on the same Open are completed sequentially and in first-in-first-out (FIFO) order.

  • The operation is canceled as specified in section 2.1.5.20.

Pseudocode for the operation is as follows:

  • When a ChangeNotifyEntry.NotifyEventList element is available:

    • If all entries from ChangeNotifyEntry.NotifyEventList fit in OutputBufferSize bytes:

      • Remove all NotifyEventEntries from ChangeNotifyEntry.NotifyEventList.

      • Copy NotifyEventEntries to OutputBuffer.

      • Set Status to STATUS_SUCCESS.

      • Set ByteCount to the size of OutputBuffer, in bytes.

    • Else:

      • Set Status to STATUS_NOTIFY_ENUM_DIR.

      • Set ByteCount to zero.

    • EndIf

  • EndIf
