There are a lot of code in the function above, but it basically does 3 steps - preparing the arguments, making the call, and building the result and propagating the arguments back (for out/inout parameters).Eventually it uses ffi_call from FFI to make the...

All python initialization module functions need to be named init<module_name> - this is how python knows which function to call in your extension module. All it needs to do right now is to register the module with the list of static methods you supplied....
You can then compare the function performance to the Python implementation.Follow these steps to call the extension module DLL from Python:Open the .py file for your Python project in the code editor. At the end of the file, add the following code to call the methods exported from the ...

The filename of the produced extension module must not be changed as Python insists on a module name derived function as an entry point, in this casePyInit_some_moduleand renaming the file will not change that. Match the filename of the source code to what the binary name should be. ...
