2. 线程的分类

---

---

3. Linux线程实现

---

3.1 线程标识

---

---

3.2 线程创建

---

---

3.2.1 线程创建实例

---

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

void* th_fn(void *arg)
{
  int distance = (int)arg;  
  int i;
  for(i = 1; i <= distance; i++){
    printf("%lx run %d\n", pthread_self(), i);
    int time = (int)(drand48()*100000);
    usleep(time);
  }  
  return (void*)0;
}
int main()
{
 int err;
   pthread_t rabbit, turtle;
   //创建rabbit线程
   if((err = pthread_create(&rabbit, NULL,
                    th_fn, (void*)50)) != 0){
     perror("pthread_create error");
   }
   //创建turtle线程
   if((err = pthread_create(&turtle, NULL, 
                    th_fn, (void*)50)) != 0){
     perror("pthread_create error");
   }
   //主控线程调用pthread_join()，自己会阻塞
   //直到rabbit&tuttle线程结束方可运行
   pthread_join(rabbit, NULL);
   pthread_join(turtle, NULL);
   
   //sleep(10);
   printf("control thread id: %lx\n", pthread_self());
   printf("finished\r\n");

   return 0;
}
