@chapter Runtime Library Routines
The runtime routines described here are defined by section 3 of the OpenMP
-specifications in version 3.0. The routines are structured in following
+specifications in version 3.1. The routines are structured in following
three parts:
Control threads, processors and the parallel environment.
* omp_get_thread_limit:: Maximum number of threads
* omp_get_thread_num:: Current thread ID
* omp_in_parallel:: Whether a parallel region is active
+* omp_in_final:: Whether in final or included task region
* omp_set_dynamic:: Enable/disable dynamic teams
* omp_set_max_active_levels:: Limits the number of active parallel regions
* omp_set_nested:: Enable/disable nested parallel regions
