Using `gawk' with BSD Portals
=============================

   Similar to the `/inet' special files, if `gawk' is configured with
the `--enable-portals' option (Note: Compiling `gawk' for Unix.
), then `gawk' treats files whose pathnames begin with
`/p' as 4.4 BSD-style portals.

   When used with the `|&' operator, `gawk' opens the file for two-way
communications.  The operating system's portal mechanism then manages
creating the process associated with the portal and the corresponding
communications with the portal's process.
