The FILE_NAME_INFORMATION structure is used as argument to the ZwQueryInformationFile and ZwSetInformationFile routines.
FileNameLengthSpecifies the length, in bytes, of the file name string.
FileNameSpecifies the first character of the file name string. This is followed in memory by the remainder of the string.
The ZwQueryInformationFile routine uses this structure to return the file name string to the caller. For more information about the form of the name returned, see ZwQueryInformationFile.
Callers of ZwSetInformationFile can use this structure to specify a new short name for a file.
This structure is documented in Windows Driver Kit.
