C语言多线程

在项目中需要写底层扩展，需要多线程的支持，写了一个例程测试一下。

#include

#define MAX 10
pthread_t thread[2];
pthread_mutex_t mut;
int number=0, i;

void *thread1() {
	printf ("thread1 : I'm thread 1\n");
	for (i = 0; i < MAX; i++) {
		printf("thread1 : number = %d\n",number);
		pthread_mutex_lock(&mut);
		number++;
		pthread_mutex_unlock(&mut);
		sleep(2);
	}
	printf("thread1 :thread 1 end\n");
	pthread_exit(NULL);
}

void *thread2() {
	printf("thread2 : I'm thread 2\n");
	for (i = 0; i < MAX; i++) {
		printf("thread2 : number = %d\n",number);
		pthread_mutex_lock(&mut);
		number++;
		pthread_mutex_unlock(&mut);
		sleep(3);
	}
	printf("thread2 :thread 2 end\n");
	pthread_exit(NULL);
}

void thread_create(void) {
	int temp;
	memset(&thread, 0, sizeof(thread)); //comment1
	
	if((temp = pthread_create(&thread[0], NULL, thread1, NULL)) != 0) //comment2
		printf("thread 1 create falut\n");
	else
		printf("thread 1 create\n");

	if((temp = pthread_create(&thread[1], NULL, thread2, NULL)) != 0) //comment3
		printf("thread 2 create falut\n");
	else
		printf("thread 2 create\n");
}

void thread_wait(void) {
	if(thread[0] !=0) { //comment4
		pthread_join(thread[0],NULL);
		printf("thread 1 end\n");
	}
	if(thread[1] !=0) { //comment5
		pthread_join(thread[1],NULL);
		printf("thread 2 end\n");
	}
}

int main() {
	pthread_mutex_init(&mut,NULL);
	printf("I am main thread, create other thread\n");
	thread_create();
	printf("I am main thread, waiting other end\n");
	thread_wait();
	return 0;
}

运行结果：

thread1 : number = 0
