[英]Is there any way to send signal to a thread from another process?
I want to send a signal from a process to a thread that is created from another process (that have not created the thread. 我想将信号从一个进程发送到另一个进程 (尚未创建该线程)创建的线程。
What I know about this that: 我对此的了解是:
raise : sends signal to same process 提高 :将信号发送到同一进程
pthread_kill can send singal to a thread from same prcess, ie that created that thread. pthread_kill可以从同一进程(即创建该线程的进程)向线程发送信号。 you cannot use pthread_kill to send a signal to thread from another process.
您不能使用pthread_kill从另一个进程向线程发送信号。
kill sends signal to a process 杀死发送信号到进程
Is there any way to send signal to a thread from another process? 有什么方法可以将信号从另一个进程发送到线程吗?
Hope I am clear!!! 希望我清楚! NOTE: I am new to unix and threading
注意:我是不熟悉Unix和线程技术的
You Should Read About 您应该阅读有关
pthread_signal()
Should set you in the right direction 应该为您设定正确的方向
There is an appropriately named tkill(2)
: 有一个适当命名的
tkill(2)
:
tkill, tgkill - send a signal to a thread tgkill() sends the signal sig to the thread with the thread ID tid
You can get a tid using gettid(2)
. 您可以使用
gettid(2)
。
Beware: the concept of a TID and therefore everything having to do with one is Linux-specific. 当心:TID的概念,因此与TID有关的一切都是特定于Linux的。
