pthread.c

linux下多线程实现生产者消费者及用并行算法求圆周率等经典算法

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

#define N 16
void *thread(void *arg)
{
     printf("Hello, world! <from %d>\n", *(int*)arg);
     return NULL;
}
int main()
{
     pthread_t tid[N];
     int i, arg[N];

     for (i=0; i<N; i++) arg[i] = i;
     
     for (i=0; i<N; i++)     
	  pthread_create(&tid[i], NULL, thread, (void *)&arg[i]);
     
     for (i=0; i<N; i++)     
	  pthread_join(tid[i], NULL);

     return 0;
}
