Choosing Among Multiple Occurrences

If multiple symbols are accessible from the same scope level, dbx prints a message reporting the ambiguity.

(dbx) func main
(dbx) which C::foo
More than one identifier ’foo’.
Select one of the following:
 0) Cancel
 1) ”a.out”t.cc”C::foo(int)
 2) ”a.out”t.cc”C::foo()
>1
”a.out”t.cc”C::foo(int)

In the context of the which command, choosing from the list of occurrences does not affect the state of dbx or the program. Whichever occurrence you choose, dbx echoes the name.
