This information class is used to query for information on a network file open. A network file open differs from a file open in that the handle obtained from a network file open can be used to look up attributes using FileNetworkOpenInformation, but it cannot be used for reads and writes to the file. The network file open is an optimization of file open that returns a file handle to the caller more quickly, but the file handle it returns cannot be used in all of the ways that a normal file handle can be used. The FILE_NETWORK_OPEN_INFORMATION data element is as follows.
