hellothread.c

linux下线程编程序事例,已经验证过了,很好用

#include <pthread.h>
#include <stdio.h>
//#define NULL 0
int  i = 0;
void *threadA(void *arc)
{
//	int i = 0;
        while(1)
        {
                printf("hello threadA***%d***times\n", i++);
          //      printf("hello threadA***%d***times\n",*(int *)arc);
                sleep(2);
         }
}
                                                                
void *threadB(void *arc)
{
    //  int i = 0; 
       while(1)
        {
                printf("hello threadB***%d***times\n", i++);
        //        printf("hello threadB***%d***times\n",*(int *)arc);
                sleep(2);
        }
}
int  main()
{
        pthread_t threadidA, threadidB;
	int arcA = 123;
	int arcB = 456;
        pthread_attr_t attr;
   	pthread_attr_init(&attr);
        pthread_attr_setdetachstate(&attr, PTHREAD_CREATE_DETACHED);
	pthread_create(&threadidA, &attr, &threadA,(int *) &arcA);
        pthread_create(&threadidB, &attr, &threadB, (int *)&arcB);
       // pthread_create(NULL, NULL, NULL, NULL);
        pthread_join(threadidA, NULL);
        pthread_join(threadidB, NULL);
	while(1)
        {
                sleep(2);
                printf("main test\n");
        }
        return 0;
