创建特定时间的线程

Question

I have written a sample program to implement array of threads.There are two thread functions. Is there any way to define a fixed value of time (in seconds) after which all the threads will automatically stop?

Sample program:

#include <stdio.h>
#include <pthread.h>
#include <stdlib.h>
#include <unistd.h>


void * threadFunc1(void * arg)
{

    int id = *((int *) arg);
    printf("Inside threadfunc2 for thread %d\n",id)
    while(1);
}

void * threadFunc2(void * arg)
{
    int i= *((int *)arg);
    printf("Inside threadfunc2 for thread %d\n",i)
    while(1);
}

int main(void)
{

    pthread_t thread[10];

    for(int i=0;i<10;i++)
    {

        pthread_create(&thread[i],NULL,threadFunc1,(void*)&i ); 
        pthread_create(&thread[i],NULL,threadFunc,(void*)&i );
    }

    for (i=0;i<total;i++)
    {
          pthread_join(thread[i],NULL);
      }
    return 0;
 }

Answer 1

Instead of waiting for the threads with pthread_join you could put your main thread to sleep, eg with nanosleep . If you then quit your main without joining, your whole process will be killed.

Answer 2

No, there is not. Threads do not 'automatically stop'
