-@subsection TASK_POST_SWITCH Extension
-
-The TASK_POST_SWITCH extension corresponds to a task
-context switch. If this extension is defined in any static or
-dynamic extension set and a raw task context switch has been
-completed, then the extension routine will automatically be
-invoked by RTEMS. The extension should have a prototype similar
-to the following:
-
-@ifset is-C
-@example
-rtems_extension user_task_post_switch(
- rtems_tcb *current_task
-);
-@end example
-@end ifset
-
-@ifset is-Ada
-@example
-procedure User_Task_Post_Switch (
- Current_Task : in RTEMS.TCB_Pointer
-);
-@end example
-@end ifset
-
-where current_task can be used to access the TCB for
-the task that is being swapped out, and heir_task can be used to
-access the TCB for the task being swapped in. This extension is
-invoked from RTEMS' dispatcher routine after the current_task
-context has been restored and the extension runs in the context
-of the current_task.
