Re: pipe to a pubprocess, or tmpfile

[Martin Voigt <voigt.m@...>]

I'm having similar problems and tried io.popen. Problem is, popen
doesn't give you the return value of the command you ran.
Unfortunately I need both, the stdout/ stderr handles and the return
value. As for now I had to go with os.execute(cmd.." >
"..tmp_file_name.." 2> "..tmp_file_name) and fiddle to get it also run
on windows xp (xp and files, what a pain..."file is used by another
process"). Are there any alternatives besides patching io.popen?
