  STREAMS 
 
    A  collection  of  {system  calls},  {kernel} 
  resources,  and  kernel  utility  routines  that  can  create,  use 
  and  dismantle  a  {stream}.  A  "stream  head"  provides  the 
  interface  between  the  stream  and  the  user  processes.  Its 
  principal  function  is  to  process  STREAMS-related  user  system 
  calls.  A  "stream  module"  processes  data  that  travel  bewteen 
  the  stream  head  and  driver.  The  "stream  end"  provides  the 
  services  of  an  external  input/output  device  or  an  internal 
  software  driver.  The  internal  software  driver  is  commonly 
  called  a  {pseudo-device}  driver. 
 
  The  STREAMS  concept  has  been  formalised  in  {Unix}  {System  V}. 
  For  example,  {SVR4}  implements  {sockets}  and  {pipes}  using 
  STREAMS,  resulting  in  pipe(2)  openning  bidirectional  pipes.
