Actually, while I'm not sure how Linux does it, on the *BSDs pipes are actually socketpairs.
This raises the question, which the documentation did not make clear to me, whether a "named pipe" is a pipe. One would hope it was, but S_IFIFO and S_IFSOCK are different...
They have to be: bound AF_UNIX sockets and fifos have very different semantics. That said, fifos could still be a different socket type, just as pipes are a distinct socket type. -- brandon s. allbery [solaris,freebsd,perl,pugs,haskell] allbery@kf8nh.com system administrator [openafs,heimdal,too many hats] allbery@ece.cmu.edu electrical and computer engineering, carnegie mellon university KF8NH
