Python ctypes: loading DLL from from a relative path

ctypes

I have a Python module, wrapper.py, that wraps a C DLL. The DLL lies in the same folder as the module. Therefore, I use the following code to load it:

myDll = ctypes.CDLL("MyCDLL.dll")

This works if I execute wrapper.py from its own folder. If, however, I run it from elsewhere, ctypes goes looking for DLL in the current working directory and naturally fails.

My question is, is there a way by which I can specify the DLL's path relative to the wrapper instead of the current working directory? This will enable me to ship the two together and allow the user to run/import the wrapper from anywhere.

When using Python CTypes there are the Structures, that allow you to clone c-structures on the Python side, and the POINTERS objects that create a sofisticated Python Object from a memory address value and can be used to pass objects by reference back and forth C code.
