[Project_owners] getting output from external process

Is there a simple way to get the output of an external process? When I
run (for example) SQLite using nsIProcess, the results scroll by in the
console window, but I can't figure out how to grab them in my extension
code. I also tried doing a stdout redirect (and read the output file
after the process terminates), but output still goes to the console and
no output file is created.
Here's the code: (Mostly taken from
// create an nsILocalFile for the executable
var file = Components.classes["@mozilla.org/file/local;1"]
// create an nsIProcess
var process = Components.classes["@mozilla.org/process/util;1"]
// Run the process.
// If first param is true, calling process will be blocked until
// called process terminates.
// Second and third params are used to pass command-line arguments
// to the process.
var args = ["C:\\temp\\test", "select * from tblReports;",
//var args = ["C:\\temp\\test", "select * from tblReports;",
process.run(true, args, args.length);
output from the process?
Thanks for any tips!
ps - Yes, I know I should just integrate SQLite via XPCOM. Has anyone
done this before? Seems like it'd be useful, but a bit daunting for my
first XPCOM project! :)
