直接看代码吧，代码里有注释
复制代码 代码如下:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <pthread.h>
#include <time.h>
#define MAX 3
int number =0;
pthread_t id[2];
pthread_mutex_t mut; //初始化静态互斥锁
void thread1(void)
{
int i;
printf("Hello,I am pthread1!n");
for (i=0; i<MAX; i++)
{
pthread_mutex_lock(&mut); //此处上锁，保证number的唯一性
number ++;
printf("Thread1:number = %dn",number);
pthread_mutex_unlock(&mut);
sleep(1); //linux c下 sleep(minute),里面变量单位是分钟
}
pthread_exit(NULL); //线程通过执行此函数，终止执行。返回是一个空指针类型
}
void thread2(void)
{
int j;
printf("Hello,I'm pthread2n");
for(j=0; j<MAX; j++)
{
pthread_mutex_lock(&mut);
number ++;
printf("Thread2:number = %dn",number);
pthread_mutex_unlock(&mut);
sleep(1);
}
pthread_exit(NULL);
}
void thread_create(void)
{
int temp;
memset(&id, 0, sizeof(id));
if(temp = pthread_create(&id[0], NULL, (void *)thread1, NULL)!= 0)
//参数：线程标识符指针 线程属性 线程运行函数起始地址 运行函数属性
//创建成功返回 0
printf("Thread 1 fail to create!n");
else
printf("Thread 1 createdn");
if(temp = pthread_create(&id[1], NULL, (void *)thread2, NULL)!= 0)
printf("Thread 2 fail to create!n");
else
printf("Thread 2 created!n");
}
void thread_wait()
{
if(id[0] != 0)
{
pthread_join(id[0], NULL); //等待线程结束，使用此函数对创建的线程资源回收
printf("Thread1 completed!n");
}
if(id[1] != 0)
{
pthread_join(id[1], NULL);
printf("Thread2 completed!n");
}
}
int main(void)
{
int i,ret1,ret2;
pthread_mutex_init(&mut, NULL); //动态互斥锁
printf("Main fuction,creating thread...n");
thread_create();
printf("Main fuction, waiting for the pthread end!n");
thread_wait();
return (0);
}
