pthread_timedjoin_np() return EBUSY 什么时候开始?
When does pthread_timedjoin_np() return EBUSY?
我正在尝试处理 pthread_timedjoin_np()
的所有可能的 return 值,但我不太明白,什么时候 return EBUSY
?
如果线程 return 在给定时间内 pthread_timedjoin_np()
始终 return 为零,而如果时间已经过去,我会得到 ETIMEDOUT
。我需要做什么才能触发 EBUSY
?
I did not quite understand, when does it return EBUSY?
从来没有。
您正在阅读的手册页适用于 pthread_tryjoin_np
和 pthread_timedjoin_np
。当“线程在调用时尚未终止”时,pthread_tryjoin_np
将 return 和 EBUSY
。
These functions can fail with the same errors as pthread_join(3).
pthread_tryjoin_np() can in addition fail with the following error:
EBUSY thread had not yet terminated at the time of the call.
pthread_timedjoin_np() can in addition fail with the following
errors:
EINVAL abstime value is invalid (tv_sec is less than 0 or tv_nsec
is greater than 1e9).
ETIMEDOUT
The call timed out before thread terminated.
