Sentinel objects
****************

PyTypeObject PySentinel_Type

   This instance of "PyTypeObject" represents the Python "sentinel"
   type.  This is the same object as "sentinel".

   Ajouté dans la version 3.15.

int PySentinel_Check(PyObject *o)

   Return true if *o* is a "sentinel" object or a subtype. The
   "sentinel" type does not currently allow subclasses, so this check
   is exact. Future Python versions may choose to allow subtyping.
   This function always succeeds.

   Ajouté dans la version 3.15.

int PySentinel_CheckExact(PyObject *o)

   Return true if *o* is a "sentinel" object, but not a subtype. The
   "sentinel" type does not currently allow subclasses. Future Python
   versions may choose to allow subtyping. This function always
   succeeds.

   Ajouté dans la version 3.15.

PyObject *PySentinel_New(const char *name, const char *module_name)
    *Valeur de retour : nouvelle référence.*

   Return a new "sentinel" object with "__name__" set to *name* and
   "__module__" set to *module_name*. *name* must not be "NULL". If
   *module_name* is "NULL", "__module__" is set to "None". Return
   "NULL" with an exception set on failure.

   For pickling to work, *module_name* must be the name of an
   importable module, and the sentinel must be accessible from that
   module under a path matching *name*.  Pickle treats *name* as a
   global variable name in *module_name* (see "object.__reduce__()").
