Debuggers

You can use the debugger to reveal the contents of Core Foundation objects, but how you use it depends on your development platform.

• Mac OS X: Because Core Foundation uses opaque types, CFShow is a convenient tool for discovering the contents of objects. Call CFShow within the debugger or programmatically on an object to print a description of that object. The description is appropriate to the type of object. For example, calling CFShow on CFNumber prints a number; for a CFArray, CFShow prints information general to the array as well as information on each element of the array.

• Mac OS 9: Because you cannot use the debugger to call functions (such as CFShow) at runtime, you must use other techniques to examine memory. Consult the Core Foundation release notes for the latest debugging tips and techniques.
