这段代码在链接的时候提示：

undefined reference to `memset'
undefined reference to `memcpy'

让 ChatGPT 给我实现了一下，编译链接进去就好了。

#include "kstring.h"
void memset(void s, int c, size_t n)
{
unsigned char p = s;
while (n--)
p++ = (unsigned char)c;
return s;
}
void memcpy(void dest, const void src, size_t n)
{
unsigned char d = dest;
const unsigned char s = src;
while (n--)
d++ = *s++;
return dest;
}
