描述

Gets information about a file.

This function gets information about the specified file asynchronously without opening the file. On completion of the asynchronous operation, the result parameter's FileInfoResult.FileState member reports whether the file exists (FileState.Exists) or not (FileState.Absent). If the file exists, the result parameter's FileInfoResult.FileSize member reports the size of the file in bytes. If the file is absent, the size is reported as zero.
