Re: redirect stderr

Having a nice little conversation with myself here, but...

After digging into this a little further, it seems that you can get the
stderr NSFileHandle from the NSFileHandle class.  It seems that one should
just be able to add oneself as an observer of
NSFileHandleReadCompletionNotification and then send the stderr filehandle
off listening via readInBackgroundAndNotify, ie:

        NSFileHandle *fh = [NSFileHandle fileHandleWithStandardError];
        [[NSNotificationCenter defaultCenter] addObserver:self
            selector:@selector(getData:)
            name: NSFileHandleReadCompletionNotification
            object: fh];
        [fh readInBackgroundAndNotify];

I've tried this, but my notification proc never gets called.  Am I missing
something here?  Anyone?

Thanks,
Jeff

| Never mind - should've checked the archives first.

| Looks like NSTask is the answer.

| | Hello,
| |
| | Is there any easy (or hard) way to redirect stderr, or more specifically
| the
| | output from NSLog?  We'd like to output it to a window in our
application.
