/**\r
  Enumerates the current set of protocol instances that abstract OS services from EFI.\r
  \r
  A given protocol can have multiple instances. Usually a protocol is configured via a\r
  single PCD string. The data associated for each instance is seperated via a ! in the string. \r
  EMU_IO_THUNK_PROTOCOL_CLOSE.ConfigString will contain the information in the PCD string up to the next !.\r
  Thus each instance has a unique ConfigString. \r
\r
  @param  EmuBusDriver          TRUE means only return protocol instances that need to be produced\r
                                by the EmuBusDriver. FALSE means return all possible protocols\r
  @param  Instance              On input the protocol to search for, or NULL to start a search \r
                                of all the supported protocol instances. \r
  @param  NextProtocol          On output it represents the next value to be passed into Protocol. \r
  @param  Interface             A pointer to the EMU_IO_THUNK_PROTOCOL_CLOSE interface. \r
\r
  @retval EFI_SUCCESS           The function completed successfully.\r
  @retval EFI_NOT_FOUND         The next protocol instance was not found.\r
  @retval EFI_INVALID_PARAMETER Instance is NULL.\r
