I/O redirection on the commandline is handled by the shell, not the
CreateProcess() function. At the Perl level, system($cmd) will scan
$cmd for the presence of any shell meta-characters, like '<', '>', '|',
'%' and maybe others I currently don't remember. If it detects any of
those, then it starts the process as "cmd.exe /c $cmd".
Win32::Process is a low level interface to the Win32 CreateProcess()
API, so I don't think it should do this type of commandline rewriting;
it should be the caller's job to do that.
If you don't want to start the subprocess via cmd.exe then you could
also re-open STDOUT and STDERR in your Perl process and set the
"inherit" parameter (the one after $command) to a true value so that
your new process inherits the file handles:
Win32::Process::Create( $processObj, $^X, $command, 1,
IDLE_PRIORITY_CLASS, $INSTDIR )
