+
+CObjects
+--------
+
+.. index:: object: CObject
+
+Refer to :ref:`using-cobjects` for more information on using these objects.
+
+
+.. ctype:: PyCObject
+
+   This subtype of :ctype:`PyObject` represents an opaque value, useful for C
+   extension modules who need to pass an opaque value (as a :ctype:`void\*`
+   pointer) through Python code to other C code.  It is often used to make a C
+   function pointer defined in one module available to other modules, so the
+   regular import mechanism can be used to access C APIs defined in dynamically
+   loaded modules.
+
+
+.. cfunction:: int PyCObject_Check(PyObject *p)
+
+   Return true if its argument is a :ctype:`PyCObject`.
+
+
+.. cfunction:: PyObject* PyCObject_FromVoidPtr(void* cobj, void (*destr)(void *))
+
+   Create a :ctype:`PyCObject` from the ``void *`` *cobj*.  The *destr* function
+   will be called when the object is reclaimed, unless it is *NULL*.
+
+
+.. cfunction:: PyObject* PyCObject_FromVoidPtrAndDesc(void* cobj, void* desc, void (*destr)(void *, void *))
+
+   Create a :ctype:`PyCObject` from the :ctype:`void \*` *cobj*.  The *destr*
+   function will be called when the object is reclaimed. The *desc* argument can
+   be used to pass extra callback data for the destructor function.
+
+
+.. cfunction:: void* PyCObject_AsVoidPtr(PyObject* self)
+
+   Return the object :ctype:`void \*` that the :ctype:`PyCObject` *self* was
+   created with.
+
+
+.. cfunction:: void* PyCObject_GetDesc(PyObject* self)
+
+   Return the description :ctype:`void \*` that the :ctype:`PyCObject` *self* was
+   created with.
+
+
+.. cfunction:: int PyCObject_SetVoidPtr(PyObject* self, void* cobj)
+
+   Set the void pointer inside *self* to *cobj*. The :ctype:`PyCObject` must not
+   have an associated destructor. Return true on success, false on failure.
