Additional macros for modules that implement new object types.
|
|
You must first include "object.h".
|
|
|
|
NEWOBJ(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.
|
|
|
|
NEWVAROBJ(type, typeobj, n) is similar but allocates a variable-size
|
|
object with n extra items. The size is computer as tp_basicsize plus
|
|
n * tp_itemsize. This fills in the ob_size field as well.
