Quoting wiki:

"""Like named pipes, Unix domain sockets support transmission of a reliable stream of bytes (SOCK_STREAM, compare to TCP). In addition, they support ordered and reliable transmission of datagrams (SOCK_SEQPACKET), or unordered and unreliable transmission of datagrams (SOCK_DGRAM, compare to UDP)."""

I'm also sure I saw that UDP can never be used as a reliable protocol in Stevens books.  (I'm sure you can google this too.)
