I've long used cygwin's nm command for all my .lib symbol debugging needs, but recently I thought about referring to it in a SO answer and realized that most Windows developers don't have cygwin installed.
So what is the Microsoft equivalent to nm, i.e., what command will list the symbols exported by a .lib file, the undefined symbols in the .lib, and so forth?
For the curious, a sample nm man page is here.
Try dumpbin.exe.
