37 PyObject_NEW(type, typeobj) allocates memory for a new object of the given |
| 6 | 38 type; here 'type' must be the C structure type used to represent the |
| 39 object and 'typeobj' the address of the corresponding type object. | |
| 40 Reference count and type pointer are filled in; the rest of the bytes of | |
| 41 the object are *undefined*! The resulting expression type is 'type *'. | |
| 42 The size of the object is actually determined by the tp_basicsize field | |
| 43 of the type object. | |
