Hey, Thanks for the response. It has helped, but I am still confused a bit by you stating that none of the types are supported but that I can still dereference a pointer. I have now been able to dereference some pointers, but not pointers to pointers. Is that what you meant? In these cases I guess I will have to create an objective-c wrapper. I found an entry on the MacRuby site about creating bundles which I think is a good solution. Thanks for the pointers, Mark Sent from my iDevice On 2010-10-24, at 3:06, Matt Aimonetti <mattaimonetti@gmail.com> wrote:
You can set pointers using:
Pointer.new_with_type and using one of the following types: http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/ObjCR... Note, that not none of the types are supported.
Here is some more information: http://jonathan.waddilove.net/macruby_pointers.html
To dereference a pointer, simply get its value:
pointer = Pointer.new_with_type("f") pointer.assign(3.2) pointer's value = pointer[0]
I'll soon update my book draft with a section on pointers.

I've been trying to play with using the Accessibility API to do some automated testing.
From what I have researched, I have to use some C functions that often need a reference passed to the them.
I am at a loss when trying to deal with Pointer objects. I've tried playing with them and googling it, but I just cannot figure out how to turn a pointer into a more useful type or to get what I want out of them.
For example, I can start like this:
framework 'Cocoa'
unless AXAPIEnabled() # only works if I include the parenthesis puts 'Please enable Access for Assistive Devices first' exit 2 end
mail = NSRunningApplication.runningApplicationsWithBundleIdentifier('com.apple.Mail').first mail_object = AXUIElementCreateApplication mail.processIdentifier
names = Pointer.new :object
AXUIElementCopyAttributeNames mail_object, names
But then how do I get the values out of the names pointer? For reference, I found the functions in AXUIElement.h.
