VOID ZeroMemory(PVOID Destination,  //指向一内存块的开始地址SIZE_T Length       // 要清零的字节数
);

• void *memset(void *s,int ch,size_t n); 

• char str[] = "almost every programmer should know memset!";
  memset (str,'-',6);
  puts (str);输出结果为
  ------ every programmer should know memset!

• ZeroMemory使用memset实现的

  • #define RtlZeroMemory(Destination,Length) memset((Destination),0,(Length))
    #define ZeroMemory RtlZeroMemory

• 使用memset可以达到ZeroMemory函数的效果
