| 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.
