     DESCRIPTION

     DESCRIPTION
     DESCRIPTION
          Pipe creates an I/O mechanism called a pipe and returns two
          file descriptors, fildes [0] and fildes [1].  Fildes [0] is
          opened for reading and fildes [1] is opened for writing.

          Writes up to 10240 bytes of data are buffered by the pipe
          before the writing process is blocked.  A read on file
          descriptor fildes [0] accesses the data written to fildes
          [1] on a first-in-first-out basis.

          No process may have more than 20 file descriptors open
          simultaneously.

          Pipe will fail if 19 or more file descriptors are currently
          open.  [EMFILE]

          indicate the error.
