NAME
     PXFPIPE - Create an inter-process channel (pipe) and return fds for the
     read and write ends of the pipe

SYNOPSIS
     SUBROUTINE PXFPIPE (ireadfd, iwrtfd, ierror)
     INTEGER ireadfd, iwrtfd, ierror

DESCRIPTION
     This routine creates a pipe and returns fds for the pipe.

     The following arguments are used in this routine:

     ireadfd   Default integer output variable containing the file descriptor
               for the read end of the pipe.

     iwrtfd    Default integer output variable containing the file descriptor
               for the write end of the pipe.

     ierror    Default integer output variable that contains zero if the
               operation was successful or nonzero if the operation was not
               successful.

     PXFPIPE may return one of the following error values:

     EMFILE      If too many file descriptors are currently open for the
                 process.

     ENFILE      If too many file descriptors are currently open for the
                 system.

NOTES
     The PXF_DEFINITIONS module can be used by Fortran 90 users to enable
     caller-callee interface checking.
