I have an Python Object with a type PySurface_Type. The Object has a method called Properties like so ->

{"Properties", (PyCFunction)Surface_set_properties, METH_VARARGS| METH_KEYWORDS, "Set the surface properties as a list of integers or keywords, e.g. set_properties(x=[int][PyList[int, ...], y=int, width=int, height=int). Note: the Python list must be the first argument or x=PyList[int, ...] "},

How can I get the doc string from this method? I would like to print this in an error message.

The docstring is available as the __doc__ attribute of the surface.Properties object ("surface" being the Python name of PySurface_Type).

In Python one would access it as surface.Properties.__doc__, which would translate to Python/C as:

const char *surface_props_doc_string() { PyObject *propdeco, *doc; const char *doc_str; propdeco = PyObject_GetAttrString((PyObject *) PySurface_Type, "Properties"); if (!propdeco) return NULL; doc = PyObject_GetAttrString(propdeco, "__doc__"); Py_DECREF(propdeco); if (!doc) return NULL; doc_str = PyString_AsString(doc); Py_DECREF(doc); return doc_str; }
