As discussed in https://stackoverflow.com/questions/62947076/replace-a-function-pointer-in-a-shared-library-with-ctypes, it seems currently not possible to replace an existing global variable in a shared library which contains a function pointer, with a callback defined in Python (through ctypes). However, it is possible to replace global variables of other types, such as `int`.
