The semantics of this function is similar to .Xr pthread_suspend_all_np 3 . .Pp The .Fn pthread_multi_np function switches the process to a multi-threaded mode. The semantics of this function is similar to .Xr pthread_resume_all_np 3 . .Sh RETURN VALUES The .Fn pthread_multi_np and .Nm pthread_single_np functions always return 0. .Sh SEE ALSO .Xr pthread_resume_all_np 3 , .Xr pthread_suspend_all_np 3 .Sh AUTHORS This manual page was written by .An Alexey Zelkin Aq Mt phantom@FreeBSD.org . |
