问题描述
在 Linux 中，在 sched.h 中定义了 sched_setaffinity()函数，但是我似乎找不到类似的东西 Mac OS X 10.6 pthreads 实现中...如果无法设置亲和力， OS X 中的默认策略是什么?
In Linux there is a sched_setaffinity() function defined in sched.h, but I can't seem to find anything like that in Mac OS X 10.6 pthreads implementation... If it is not possible to set affinity, what is the default policy in OS X?
推荐答案
Mac OS X has Thread Affinity API and you can use it with pthread ID as thread_policy_set(pthread_mach_thread_np(pthreadId), but, as far as I know, there are no APIs like sched_setaffinity.
