Hi there, I wonder what's the best way to wrap given function calls (in this case ctype function calls but more generally built-in functions and those kinds). I have a huge c library and almost all functions return an error code. The library also contains a function, that returns the corresponding error message to the error code. So, what I need to do for every call to one of the libraries functions looks like this:
error_code = my_c_library.SOME_FUNCTION_ CALL(argument) if error_code != 0: error_message = my_c_library.GET_ERROR_TEXT(error_code) print "error in function call SOME_FUNCTION_CALL" print error_message my_c_library.EXIT_AND_CLEAN_UP() Also, for some function calls I would need to do some preperations like: error_code = my_c_library.LOG_IN_AS_ADMINISTRATOR(admin_user, admin_password) error_code = my_c_library.SOME_FUNCTION_CALL(argument) I like the decorator idea, but I can't figure out if it's applicable here. To be able to call the function in a manner like this would be great, e.g. @change_user(admin_user, admin_password) @error_handling my_c_library.SOME_FUNCTION_CALL(argument) Best regards, Jan
