SUMMARY
The discussion addresses the challenge of terminating child threads (b and c) from another child thread (b) in a C++ program. The recommended solution involves using the thread IDs of the child threads, which should be stored in a global structure by the parent thread upon creation. The function pthread_kill() is suggested for terminating the threads, ensuring that the calling thread is the last to be killed. An alternative approach is to send a SIGUSER1 signal from thread b to the parent, prompting the parent to terminate all threads.
