Example 1 with LARGE_INTEGER

use of com.sun.jna.platform.win32.WinNT.LARGE_INTEGER in project jna by java-native-access.

the class Kernel32Test method testFileTimeFromLargeInteger.

        Kernel32.INSTANCE.FileTimeToSystemTime(ft, stUTC);
        // Covert to local
        Kernel32.INSTANCE.SystemTimeToTzSpecificLocalTime(null, stUTC, stLocal);
        FileTime calculatedCreateTime = FileTime.fromMillis(stLocal.toCalendar().getTimeInMillis());
        // Actual file's createTime
        FileTime createTime = Files.getLastModifiedTime(Paths.get(tmp.getAbsolutePath()));
        assertEquals(createTime.toMillis(), calculatedCreateTime.toMillis());
    } finally {
        Kernel32.INSTANCE.CloseHandle(hFile);
    }
}

Example 2 with LARGE_INTEGER
