I tried to post this via the SourceForge bug reporting, but it did not
work, so I am posting this to Raph Levien and the LPRng mailing list
in hopes that somebody can solve this one.
Version:AFPL Ghostscript 7.04
System: FreeBSD 4.5/RedHat Linux
Problem: when using pdf2ps and with input from STDIN and output to STDOUT
it gives and error. I have include a trace of the problem below. The
problem seems to be that when you specify input as 'stdin' or '-' then
the setfileposition operator fails. For example, the ifhp uses GhostScript
(actually the guts from the pdf2ps program that in turn uses ghostscript)
to do PDF to Postscript conversion. Here is a trace of the operations:

I also tried the following script (/tmp/d):
#/bin/sh
/bin/sh -c '(/usr/local/bin/gs -q -dNOPAUSE -dBATCH -dSAFER -sDEVICE=pswrite
-sOutputFile=/dev/fd/3 3>&1 1>&2 -c save pop -f -)' </tmp/one.pdf
h110: {199} % sh /tmp/b >/tmp/d
Error: /ioerror in --setfileposition--
Operand stack:
--nostringval-- --nostringval-- 0
Execution stack:
%interp_exit .runexec2 --nostringval-- --nostringval-- --nostringval-- 2
%stopped_push --nostringval-- --nostringval-- --nostringval-- false 1
%stopped_push 1 3 %oparray_pop --nostringval-- --nostringval--
--nostringval-- --nostringval-- --nostringval--
Dictionary stack:
--dict:1007/1123(ro)(G)-- --dict:0/20(G)-- --dict:71/200(L)--
--dict:71/200(L)-- --dict:97/127(ro)(G)-- --dict:220/230(ro)(G)--
--dict:7/15(L)--
Current allocation mode is local
Last OS error: 13
AFPL Ghostscript 7.04: Unrecoverable error, exit code 1
If I use:
/bin/sh -c '(/usr/local/bin/gs -q -dNOPAUSE -dBATCH -dSAFER -sDEVICE=pswrite
-sOutputFile=/dev/fd/3 3>&1 1>&2 -c save pop -f /dev/fd/0)' </tmp/one.pdf
Then there are no errors and things are fine.
Do you have any suggestions on this?
