1555  如果check_pointer( & buf, end, ptr, spec)则返回:buf
1559  当:fmt[1]恒等于'6'
1560  返回:ip6_addr_string(buf, end, ptr, spec, fmt)
1561  当:fmt[1]恒等于'4'
1562  返回:ip4_addr_string(buf, end, ptr, spec, fmt)
1563  当:fmt[1]恒等于'S'
1564  const union{struct sockaddr raw;struct sockaddr_in v4;struct sockaddr_in6 v6;} * sa = ptr
1571  当:address family, AF_xxx 恒等于Internet IP Protocol
1572  返回:ip4_addr_string_sa(buf, end, & v4, spec, fmt)
