nm(1) lists all symbol names and shows address, scope, symbol type and the location of the
symbol in the object.
main has an external scope which means it is globally accessible, a type of entry/FUNC means
that the symbol is inside the object, and it is contained in the code section of the object. The
scope of printf is undefined, it is only a code reference. The value column shows the location
(address) of the symbol inside the object.
For 64-bit objects, the nm(1) output looks somewhat different, but basically contains the same
information:
$ nm HelloWorld.o
