I've a problem with dll function colled with python/ctypes. My

same as value_type; - mydll.foo1(value_type)
same as *value_type; - mydll.foo2(*value_type)
same as **value_type; - mydll.foo3(**value_type)

How can pass it in python. If i do that:
rules=POINTER(value_type)
opr=rsl.StrengthOfRules(rules,10)
R=POINTER(rules)

POINTER takes a class and returns a new class which represents a pointer
to input class.

pointer takes an instance and returns a new object which represents a
pointer to that instance.

so,
if I write this:
p=pointer(value_type)
mydll.foo1(p)
could be correct but python say me:
TypeError: _type_ must have storage info
what does mean?

thank you
