Hi,

I'm using the CTYPES module of python to load a dll. My dll contains a
Get_Version function as:
long __stdcall af1xEvdoRDll_GetVersion(long version[4]);

This function accepts a long array of 4 elements.

Following is the python code I've written:

from ctypes import *
abc = windll.af1xEvdoRDll
GetVersion = abc.af1xEvdoRDll_GetVersion
print GetVersion
versionArr = c_long * 4 #array of 4 longs
version = versionArr(0, 0, 0, 0) # initializing all elements to 0
GetVersion(version) #calling dll function
print version

I'm getting the following output:
<_FuncPtr object at 0x00A1EB70>
<__main__.c_long_Array_4 object at 0x00A86300>

But I'm not getting the desired output which I expect as : 2.1.5.0


Please suggest what am I missig?

Don't print the object, print it's contents:

for i in xrange(4):
print version[i]

Might be that you can iterate over the array directly, not sure right now.
