This function is part of the PlayerDataStorage Interface.
Remarks
Retrieve the contents of a specific file, potentially downloading the contents if we do not have a local copy, from the cloud. This request will occur asynchronously, potentially over multiple frames. All callbacks for this function will come from the same thread that the SDK is ticked from. If specified, the FileTransferProgressCallback will always be called at least once if the request is started successfully.
Return Value
A valid Player Data Storage File Request handle if successful, or NULL otherwise. Data contained in the completion callback will have more detailed information about issues with the request in failure cases. This handle must be released when it is no longer needed
Return Value
-
EOS_Success if the file is exists and the read operation completes successfully
-
EOS_NotFound if no file is found
