STINNER Victor <vstin...@python.org> added the comment:
PyType_FromSpec() and PyType_Spec API are not currently compatible with opaque
PyObject.
Example:
---
#define PyObject_HEAD PyObject ob_base;
typedef struct {
PyObject_HEAD
...
} MyObject;
static PyType_Spec type_spec = {
.name = "MyObject",
.basicsize = sizeof(MyObject),
...
};
... = PyType_FromSpec(&type_spec);
---
sizeof(MyObject) requires to compute sizeof(PyObject).
