Linux下C编程：线程互斥实例

/*编译时留意，要手动毗连库*/ 
#include <stdio.h>       
#include <pthread.h>       
#include <unistd.h>       
#include <stdlib.h>       

static int value = 0;       
pthread_mutex_t mutex;       

void func(void* args)
{       
    while(1)       
    {       
        pthread_mutex_lock(&mutex);       
        sleep(1);       
        value ++;       
        printf("value = %d!\n", value);       
        pthread_mutex_unlock(&mutex);       
    }       
}       

int main()       
{       
    pthread_t pid1, pid2;       
    pthread_mutex_init(&mutex,NULL);         
          
    if(pthread_create(&pid2,NULL,&func,NULL))       
    {       
        return -1;       
    }       
          
    if(pthread_create(&pid1,NULL,&func,NULL))       
    {       
        return -1;       
    }       
    while(1)       
        sleep(0);
