| 31 | NEWOBJ(type, typeobj) allocates memory for a new object of the given |
| 32 | type; here 'type' must be the C structure type used to represent the |
| 33 | object and 'typeobj' the address of the corresponding type object. |
| 34 | Reference count and type pointer are filled in; the rest of the bytes of |
| 35 | the object are *undefined*! The resulting expression type is 'type *'. |
| 36 | The size of the object is actually determined by the tp_basicsize field |
| 37 | of the type object. |
| 38 | |
| 39 | NEWVAROBJ(type, typeobj, n) is similar but allocates a variable-size |
| 40 | object with n extra items. The size is computer as tp_basicsize plus |
| 41 | n * tp_itemsize. This fills in the ob_size field as well. |
