It's often easiest to find an example that includes all the fields you need (even if they're initialized to ``0``) and then change the values to suit your new type. :: - char *tp_name; /* For printing */ + const char *tp_name; /* For printing */ The name of the type - as mentioned in the last section, this will appear in various places, almost entirely for diagnostic purposes. Try to choose something that will be helpful in such a situation! :: - int tp_basicsize, tp_itemsize; /* For allocation */ + Py_ssize_t tp_basicsize, tp_itemsize; /* For allocation */ These fields tell the runtime how much memory to allocate when new objects of this type are created. Python has some built-in support for variable length structures (think: strings, lists) which is where the :c:member:`~PyTypeObject.tp_itemsize` field comes in. This will be dealt with later. :: - char *tp_doc; + const char *tp_doc; Here you can put a string (or its address) that you want returned when the Python script references ``obj.__doc__`` to retrieve the doc string. |
