 .. cfunction:: PyObject* PyCapsule_New(void* pointer, const char* name, PyCapsule_Destructor destructor)
 
    Create a :ctype:`PyCapsule` encapsulating the *pointer*.  The *pointer*
    argument may not be *NULL*.
 
-   The *name* string may either be *NULL* or a pointer to a valid
-   C string.  If non-*NULL*, this string must outlive the capsule.
-   (Though it is permitted to free it inside the *destructor*.)
-
-   If the *destructor* argument is not *NULL*,
-   it will be called with the capsule ``PyObject *`` when it is destroyed.
-
-   If this capsule will be stored as an attribute of a module, it
-   is strongly suggested that the *name* string be specified as::
-
-      modulename.attributename
-
-   This will enable other modules to import the capsule
-   using :cfunc:`PyCapsule_Import`.
-
-   Return a valid capsule on success.
    On failure, set an exception and return *NULL*.

-   *name* parameter.  (See :cfunc:`PyCapsule_GetPointer` for
