  17.      The devices known as _tttt_iiii_cccc_llll_tttt_ssss, _tttt_iiii_cccc_oooo_tttt_ssss, and _tttt_iiii_cccc_oooo_tttt_ssss_oooo_rrrr_dddd are ``loopback
  18.      transport providers,'' that is, stand-alone networks at the transport
  19.      level.  Loopback transport providers are transport providers in every
  20.      sense except one:  only one host (the local machine) is ``connected to''
  21.      a loopback network.  Loopback transports present a TPI (_SSSS_TTTT_RRRR_EEEE_AAAA_MMMM_SSSS-level)
  22.      interface to application processes and are intended to be accessed via
  23.      the TLI (application-level) interface.  They are implemented as clone
  24.      devices and support address spaces consisting of ``flex-addresses,''
  25.      i.e., arbitrary sequences of octets, of length > 0, represented by a
  26.      _nnnn_eeee_tttt_bbbb_uuuu_ffff structure.
  27.  
  28.      _tttt_iiii_cccc_llll_tttt_ssss is a datagram-mode transport provider.  It offers (connectionless)
  29.      service of type _TTTT______CCCC_LLLL_TTTT_SSSS.  Its default address size is _TTTT_CCCC_LLLL______DDDD_EEEE_FFFF_AAAA_UUUU_LLLL_TTTT_AAAA_DDDD_DDDD_RRRR_SSSS_ZZZZ.
  30.      _tttt_iiii_cccc_llll_tttt_ssss prints the following error messages (see _tttt______rrrr_cccc_vvvv_uuuu_dddd_eeee_rrrr_rrrr(3N)):

  38.      (connection-oriented) service of type _TTTT______CCCC_OOOO_TTTT_SSSS.  Its default address size
  39.      is _TTTT_CCCC_OOOO______DDDD_EEEE_FFFF_AAAA_UUUU_LLLL_TTTT_AAAA_DDDD_DDDD_RRRR_SSSS_ZZZZ.  _tttt_iiii_cccc_oooo_tttt_ssss prints the following disconnect messages
  40.      (see _tttt______rrrr_cccc_vvvv_dddd_iiii_ssss(3N)):

  46.  
  47.      _tttt_iiii_cccc_oooo_tttt_ssss_oooo_rrrr_dddd is a virtual circuit-mode transport provider, offering service
  48.      of type _TTTT______CCCC_OOOO_TTTT_SSSS______OOOO_RRRR_DDDD (connection-oriented service with orderly release).
  49.      Its default address size is _TTTT_CCCC_OOOO_OOOO______DDDD_EEEE_FFFF_AAAA_UUUU_LLLL_TTTT_AAAA_DDDD_DDDD_RRRR_SSSS_ZZZZ.  _tttt_iiii_cccc_oooo_tttt_ssss_oooo_rrrr_dddd prints the
  50.      following disconnect messages (see _tttt______rrrr_cccc_vvvv_dddd_iiii_ssss(3N)):

  74. USAGE
  75.      Loopback transports support a local IPC mechanism through the TLI
  76.      interface.  Applications implemented in a transport provider-independent
  77.      manner on a client-server model using this IPC are transparently
  78.      transportable to networked environments.
  79.  
  80.      Transport provider-independent applications must not include the header
  81.      files listed in the synopsis section above.  In particular, the options
  82.      are (like all transport provider options) provider dependent.
  83.  
  84.      _tttt_iiii_cccc_llll_tttt_ssss and _tttt_iiii_cccc_oooo_tttt_ssss support the same service types (_TTTT______CCCC_LLLL_TTTT_SSSS and _TTTT______CCCC_OOOO_TTTT_SSSS)
  85.      supported by the OSI transport-level model. The use of _tttt_iiii_cccc_llll_tttt_ssss and _tttt_iiii_cccc_oooo_tttt_ssss
  86.      _iiii_ssss _eeee_nnnn_cccc_oooo_uuuu_rrrr_aaaa_gggg_eeee_dddd_....
  87.  
  88.      _tttt_iiii_cccc_oooo_tttt_ssss_oooo_rrrr_dddd supports the same service type (_TTTT______CCCC_OOOO_TTTT_SSSS_OOOO_RRRR_DDDD) supported by the
  89.      TCP/IP model.  The use of _tttt_iiii_cccc_oooo_tttt_ssss_oooo_rrrr_dddd is discouraged except for reasons of
  90.      compatibility.
