-The user extensions manager allows the application developer to augment the

-critical system events. The directives provided by the user extensions manager
-are:
-
-- rtems_extension_create_ - Create an extension set
-
-- rtems_extension_ident_ - Get ID of an extension set
-
-- rtems_extension_delete_ - Delete an extension set

extension. Usually, the initial extension set of board support package
provides a fatal error extension which resets the board. In this case, the

-DESCRIPTION:
-
- This directive creates an extension set object and initializes it using the
- specified extension set table. The assigned extension set identifier is
- returned in :c:data:`id`. This identifier is used to access the extension
- set with other user extension manager directives. For control and
- maintenance of the extension set, RTEMS allocates an Extension Set Control
- Block (ESCB) from the local ESCB free pool and initializes it. The
- user-specified :c:data:`name` is assigned to the ESCB and may be used to
- identify the extension set via
- :ref:`rtems_extension_ident() <rtems_extension_ident>`. The extension set
- specified by :c:data:`table` is copied to the ESCB.
-
-NOTES:
- This directive may cause the calling task to be preempted due to an
- obtain and release of the object allocator mutex.
