I sent a vague message to the list a few days ago about popen2.
Having received no response, I decided to post a more specific example
of my problem.
The follwing code comes directly from the octave info pages:
[in, out, pid] = popen2 ("sort", "-nr");
fputs (in, "these\nare\nsome\nstrings\n");
fclose (in);
while (isstr (s = fgets (out)))
fputs (stdout, s);
endwhile
fclose (out);
if I execute these comamnds interactively, they _always_ produce the
correct result. When I place them in a file and call them as a
script, I either get no result at all or a warning that there is a
broken pipe and (of course) no result.
Does anyone have an idea of what the problem might be?
TIA,
A.
p.s. NetBSD 1.2.1, P133, octave 2.0.5
