RTEMS C User's Guide
When a task is created, RTEMS generates a unique task ID and
assigns it to the created task until it is deleted. The task ID
may be obtained by either of two methods. First, as the result
of an invocation of the rtems_task_create
directive, the task ID is
stored in a user provided location. Second, the task ID may be
obtained later using the rtems_task_ident
directive. The task ID is
used by other directives to manipulate this task.
