- Additional macros for modules that implement new object types.
- You must first include "object.h".
-
- PyObject_NEW(type, typeobj) allocates memory for a new object of the given
- type; here 'type' must be the C structure type used to represent the
- object and 'typeobj' the address of the corresponding type object.
- Reference count and type pointer are filled in; the rest of the bytes of
- the object are *undefined*! The resulting expression type is 'type *'.
- The size of the object is actually determined by the tp_basicsize field
- of the type object.
-
- PyObject_NEW_VAR(type, typeobj, n) is similar but allocates a variable-size
- object with n extra items. The size is computed as tp_basicsize plus
- n * tp_itemsize. This fills in the ob_size field as well.
