Programmatically enumerate symbols in a dynamic library on Mac OS X

I need a way to enumerate symbols and their addresses exported from dylibs on Mac OS X.

From the shell I would normally use nm for this - is there a library which I can use from my code to get the same things that nm provides? Similar to the dbghelp API on Windows.

As a last resort I suppose I could spawn nm and parse the output but I'm keen to avoid this if there is a cleaner method.

nm (and otool) have the knowledge built into them rather than using an API. The best you will get is header files defining the file format (see 'man Mach-O'). I would invoke nm and parse the output; there's nothing wrong with reusing an existing component just because the interface is program execution rather than function call.
