For example:

GetDiskFreeSpaceEx = Win32API.new("kernel32", "GetDiskFreeSpaceEx",
['p','p','p','p'], 'i')

def get_disk_free_space(path)
    free_caller = " " * 8
    total = " " * 8
    free = " " * 8
    GetDiskFreeSpaceEx.call(path, free_caller, total, free)
    l,h = free_caller.unpack("II")
    l + (h << 32)
end

puts get_disk_free_space("C:")
