Specifies the versions of the update sequence number (USN) change journal supported by the application. This structure is the input structure to the FSCTL_READ_FILE_USN_DATA control code.
Syntax
typedef struct {
WORD MinMajorVersion;
WORD MaxMajorVersion;
} READ_FILE_USN_DATA, *PREAD_FILE_USN_DATA;
Members
MinMajorVersion
The lowest version of the USN change journal accepted by the application. If the input buffer is not specified this defaults to 2.
MaxMajorVersion
