pthreads signal a specific thread

Question

In pthreads, is it possible for a thread to wake up another thread given only the other thread's id ?

(Kind of like, calling pthread_cond_signal() but with also a specific, known, thread id in mind)

Answer 1

您可以尝试使用sigaction()和pthread_kill() 。

Answer 2

See the discussion between @Sam Hocevar and myself in response to this question ; the documentation says pthread_kill(3) delivers a signal to a specific thread, and I'm less sure about the Linux implementation sticking true to this requirement.
