memcpy.c

用于汇编领域的,运用于OS的MAIN函数.基于硬件基础的源代码

void mymemcpy(char *dest, char *src, int len){
// don't use "memcpy". this word seems to be used in special way by the
// compiler. 
   int i;
   printk("in memcpy\n"); 
   printk("src(%x) is: ",  src);
   for(i=0;i<len;i++)
      printk("%x ", src[i]);

   for(i=0;i<len;i++)
      dest[i]=src[i];
   printk("aft memcpy. dest(%x) is: ",  dest);
   for(i=0;i<len;i++)
      printk("%x ", dest[i]);

}
