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 block::block
Class block has more than one function member named block.

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 merely echoes the name.

Remember that the which command tells you which symbol dbx would pick. In the case of ambiguous names, the overload display list indicates that dbx does not yet know which occurrence of two or more names it would use. dbx lists the possibilities and waits for you to choose one.
