返回类型：char

参数：

类型参数名称
char *buf
char *end
const u8 *addr
struct printf_specspec
const char *fmt
1663  p等于uuid
1665  index等于uuid_index
1666  bool uc = false
1668  如果check_pointer( & buf, end, addr, spec)则返回:buf
1672  当:* == 'L'
1673  uc = true
1674  当:* == 'l'
1675  index等于guid_index
1676  退出
1677  当:* == 'B'
1678  uc = true
1679  退出
1682  以i小于16循环
1683  如果uc则p等于hex_byte_pack_upper(p, addr[index[i]])
1685  否则p等于hex_byte_pack(p, addr[index[i]])
1688  当:i恒等于3
1689  当:i恒等于5
1690  当:i恒等于7
1691  当:i恒等于9
1692  p自加等于'-'
1693  退出
1697  p等于0
1699  返回:Handle string from a well known address.
