Clipboard? Copy/Paste?

Why not hook your code up to a Cocoa UI? Most of the AppKit controls that support editing will support cut and paste, and the Xcode Cocoa template includes an operating standard menu with all the right shortcuts. If you're using Xcode (or gcc by itself if you know the right flags), I think C++ can be mixed with Obj-C almost as easily as straight C. At the very worst you'll need separate files bridged with C functions.

Uh oh... Wait! don't click Post Message, I already see the problem. You need to use that expensive compiler of yours that won't support any of the above, right? And we've already been over why its libraries won't link to a gcc front end? Oh well.. Yet another happy thought shot down in flames.

I'm sorry I don't know anything about building a Carbon UI. I'm sure someone else here can help you with that, though.

All the best,

Is this a command-line app or GUI?
