windows c语言创建线程

最近须用c语言编程，需要创建进程或者线程，但是查阅了两种创建线程的方法都报错，是怎么回事？

#include
#include
#include 
/* 线程函数声明 */
void Thread1(void*);
void Thread2(void*);
//unsigned int __stdcall Thread1ex(void*);
//unsigned int __stdcall Thread2ex(void*);

/* 线程句柄 */
HANDLE h1, h2;

int main(int argc, const char** argv) {
    h1 = (HANDLE)_beginthread(Thread1, 0, NULL);//线程1
    h2 = (HANDLE)_beginthread(Thread2, 0, NULL);//线程2
    //h1 = (HANDLE)_beginthreadex(NULL, 0, Thread1ex, NULL, 0, NULL);
    //h2 = (HANDLE)_beginthreadex(NULL, 0, Thread2ex, NULL, 0, NULL);

    WaitForSingleObject(h1, INFINITE);//等待线程1结束
    WaitForSingleObject(h2, INFINITE);//等待线程2结束
    //system("pause");

    printf("主线程结束\n");
    return 0;
}
/* 线程1 */
void Thread1(void* arg)
{
    while (1)
    {
        printf("Thread1\n");
        Sleep(100);
    }
}
/* 线程2 */
void Thread2(void* arg)
{
    while (1)
    {
        printf("Thread2\n");
        Sleep(100);
    }
}

报了一堆错误，也尝试了createthread，也会报出上面的错误，该怎么解决

文件没保存吧？sleep 都是小写字母吧
