DESCRIPTION

The pthread_single_np() function switches the process to a single-threaded mode, i.e., suspends all threads except the current. The semantics of this function is similar to pthread_suspend_all_np(3).

The pthread_multi_np() function switches the process to a multi-threaded mode. The semantics of this function is similar to pthread_resume_all_np(3).

RETURN VALUES

The pthread_multi_np() and pthread_single_np functions always return 0.
