46 function switches the process to a single-threaded mode, i.e.,
47 suspends all threads except the current.
48 The semantics of this function is similar to
49 .Xr pthread_suspend_all_np 3 .
53 function switches the process to a multi-threaded mode.
54 The semantics of this function is similar to
55 .Xr pthread_resume_all_np 3 .
61 functions always return 0.
