Questions about pointers

Hi everyone,
I’m starting to use ctypes pointer in my applications ad I have some doubts. 
Consider this scenario.

lib = cdll.LoadLibrary(“MyLib.dll”)
c = POINTER(c_int)()
lib.MyAllocInt(byref(c), c_int(10))

Then ‘c’ is allocated and it contains 10 integers. Now if I do the following:

print c[0]

I get 0 while I expect c_int(0), can anyone explain me this?

Furthermore this creates me a problem. Let’s consider this example, in which I want ‘c’ to be filled with the output of a given function:

for i in range(10):
    lib.MyFunction(c_int(i), c_int(i+1), byref(c[i]))

I get an error since byref() expects a c_int, while c[i] is an integer. So I have to do:

for i in range(10):
    t = c_int(0)
    lib.MyFunction(c_int(i), c_int(i+1), byref(t))
    c[i] = t.value

which is pretty .uncomfortable. Is there a smarter way to achieve this? Thanks in advance!
