What are the semantics of the "type" argument for PyCObject_FromVoidPtr()?
From the patch, from the documentation comment above the prototype for
PyCObject_FromVoidPtr() in Include/cobject.h:
The "type" string must point to a legal C string of non-zero length,
-Does it do a strdup, or is the type required to be valid while the object
exists (e.g. a static string)?
From the patch, continuing on from where we just left off:
and this string must outlive the CObject.
-How is the type match determined, strcmp, or pointer comparison?
From the patch, observing the code in the static function
_is_legal_cobject_and_type() in Objects/cobject.c:
if (!type || !*type) {
PyErr_SetString(PyExc_TypeError, invalidType);
return 0;
}
if (strcmp(type, self->type)) {
PyErr_SetString(PyExc_TypeError, incorrectType);
return 0;
}
A method for answering further such questions suggests itself,
