linux c的sleep 和多线程测试

一直担心在线程里加sleep会引起进程所有的线程挂起，测试过了不会

 

#include <pthread.h>
#include <stdio.h>
#include <sys/time.h>
#include <string.h>
#include <unistd.h>
#define MAX 10

pthread_t thread[2];
void * thread1()
{
    while(1)printf ("thread1 : I'm thread 1\n");
}
void * thread2()
{
    printf("thread2 : I'm thread 2\n");
    sleep(3);
    printf("thread2 : I'm thread 2 end\n");
    exit(0);
}
void thread_create(void)
{
int temp;
memset(&thread, 0, sizeof(thread));
if((temp = pthread_create(&thread[0], NULL, thread1, NULL)) != 0)
printf("create thread 1 fail\n");
else
printf("create thread 1 success\n");
if((temp = pthread_create(&thread[1], NULL, thread2, NULL)) != 0)
printf("create thread 2 fail\n");
else
printf("create thread 2 success\n");
}
void thread_wait(void)
{
    if(thread[0] !=0) { //comment4
pthread_join(thread[0],NULL);
printf("thread1 end\n");
}
if(thread[1] !=0) { //comment5
pthread_join(thread[1],NULL);
printf("thread2 end\n");
}
}
int main()
{
printf("i am main\n");
thread_create();
printf("mail waitin \n");
thread_wait();
return 0;
}
