  34 Additional macros for modules that implement new object types.
  35 You must first include "object.h".
  36
  37 PyObject_NEW(type, typeobj) allocates memory for a new object of the given
  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.
  44
  45 PyObject_NEW_VAR(type, typeobj, n) is similar but allocates a variable-size
  46 object with n extra items.  The size is computed as tp_basicsize plus
  47 n * tp_itemsize.  This fills in the ob_size field as well.
