Linux下一个简单的多线程互斥锁的例子

本篇文章是对Linux下一个简单的多线程互斥锁的例子进行了分析介绍，需要的朋友可以参考下

复制代码 代码如下:

#include <stdio.h>
#include <pthread.h>
pthread_mutex_t Device_mutex ;
int count=0;
void thread_func1()
{
while(1)
{
pthread_mutex_lock(&Device_mutex);
printf("thread1: %dn",count);
pthread_mutex_unlock(&Device_mutex);
count++;
sleep(1);
}
}
void thread_func2()
{
while(1)
{
pthread_mutex_lock(&Device_mutex);
printf("thread2: %dn",count);
pthread_mutex_unlock(&Device_mutex);
count++;
sleep(1);
}
}
int main()
{
pthread_t thread1, thread2;
pthread_mutex_init(&Device_mutex,NULL);
if(pthread_create(&thread1,NULL,(void*)thread_func1,NULL) == -1)
{
printf("create IP81 Thread error !n");
exit(1);
}
sleep(1);
if(pthread_create(&thread2,NULL,(void *)thread_func2,NULL) == -1)
{
printf("create IP81_2 Thread error!n");
exit(1);
}
sleep(1);
pthread_join(thread1,NULL);
pthread_join(thread2,NULL);
pthread_mutex_destroy(&Device_mutex);
return 0;
}
