You want TN2124, "Mac OS X Debugging Magic" <http://developer.apple.com/library/mac/#technotes/tn2124/_index.html>, in the Some Assembly Required section. It shows how you can use the ABI to pull arguments. There will probably be a lot of calls, so I'd set the breakpoint to not pause the program, and attach debugger commands to print the argument values. The transcript will be huge, but the only report you're interested in is the last one. There's probably something awesome you can do with DTrace, which I'd turn to if the lldb approach didn't work, but I don't have the chops to suggest a script off the top of my head. — F -- Fritz Anderson Xcode 4 Unleashed: 4.5 supplement for free! http://www.informit.com/store/xcode-4-unleashed-9780672333279 _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
