Please use the method 'struct' like 'extern', and the following example
shows how to use it.


require 'dl/import'
require 'dl/struct'

module MyLIB
   extend DL::Importable

   MyStruct = struct [
     "int foo[3]",
   ]
end

ptr = MyLIB::MyStruct.malloc()
ptr.foo = [0,1,2]
p ptr.foo


But I found a bug on 'dl/struct.rb', so please replace it with the following file.
