Table 50 – GenerateFileForRead Method Arguments

Argument	Description
generateOptions	The structure used to define the generate options for the file, described in Section 12.11.
fileNodeId	NodeId of the temporary file
fileHandle	The fleHandle of the opened TransferFile. The fileHandle can be used to access the TransferFile methods Read and Close.
completionStateMachine	If the creation of the file is completed asynchronously, the parameter returns the NodeId of the corresponding FileTransferStateMachineType Object. If the creation of the file is already completed, the parameter is null. If a FileTransferStateMachineType object NodeId is returned, the Read Method of the file fails until the TransferState changed to ReadTransfer.
