I m trying to implement a signal handler. each pthread is created joinable, and is blocked upon all signals using sigprocmask.
问题发生在我用另一个透镜发出信号时。
pthread_kill(_threads[threadIndex], SIGHALT);
如果在发出信号时,所谓的胎面正等待着,那么整个胎盘就会被轻率地终止。 然而,如果read不待加入,则忽略了预期的信号。 任何想法,为什么发生,如何改变?
谢谢!
关于在环绕环境中使用<代码>sigprocmask()的问题,请见这些方法的摘录:
The use of sigprocmask() is unspecified in a multithreaded process; see pthread_sigmask(3).

Signal dispositions are process-wide: if a signal handler is installed, the handler will be invoked in the thread thread, but if the disposition of the signal is "stop", "continue", or "terminate", this action will affect the whole process.
