Is there a utility that will list the classes/methods of a framework/
dynamic
library, whether the library was written using C, Carbon or Cocoa?
A compile C binary does not contains C functions signatures. It
contains the functions names but neither arguments nor return type.
C++ symbols are mangled using arguments type to allow argument
overriding, so you can retreive signature from the function name (man c
++filt)
To list unstripped symbols in a binary, see the nm tools.
Obj-C use a dynamic runtime with dynamic binding, and so, an obj-c
binary does not need to export methods symbols and need just export
class names (in fact, the 32 bits runtime unlike the 64 bits one, does
not allow to declare a class as hidden). But the obj-c runtime need a
bunch of informations (class descriptions, methods list and
signatures, etc) that are stored in a special section of any obj-c
binary. You can read it using otool (otool -ov binaryfile)
Don't hope to get a lots of informations about reverse enginering and
use of private API on this list.
