[C++-sig] Passing pointer to c++ functions.
Hi, How do we pass a pointer to a c++ function from python. I have to call the below mentioned function from python long afSigGenDll_Manual_LevelMax_Get(afSigGenInstance_t sigGenId, double* pLevelMax); When i am calling the function with the second argument as pLevelMax = pointer(c_double()) its giving me an error: Traceback (most recent call last): File "", line 1, in TypeError: in method 'afSigGenDll_Manual_LevelMax_Get', argument 2 of type 'double *' Please le me know what is the correct way to pass pointers as arguments to c++ functions. Thanks in advance Regards, Yamini ___ Cplusplus-sig mailing list Cplusplus-sig@python.org http://mail.python.org/mailman/listinfo/cplusplus-sig

Python needs to execute the init function in the first module. I.e. you have to have an import from Python. You could do the Python import from the init of the second module, but for quick testing, just insert the import somewhere so that it appears before you expect the dynamic_cast to work. ___ Cplusplus-sig mailing list Cplusplus-sig@python.org http://mail.python.org/mailman/listinfo/cplusplus-sig

The second module is linked against the first one, so I think that the linker should load all shared libraries before any python::boost code get executed. > Ralf > ___ > Cplusplus-sig mailing list > Cplusplus-sig@python.org > http://mail.python.org/mailman/listinfo/cplusplus-sig > ___ Cplusplus-sig mailing list Cplusplus-sig@python.org http://mail.python.org/mailman/listinfo/cplusplus-sig
