To print a list of all the occurrences of a specified symbol, use whereis symbol, where symbol can be any user-defined identifier. For example:
(dbx) whereis table forward: `Blocks`block_draw.cc`table function: `Blocks`block.cc`table::table(char*, int, int, const point&) class: `Blocks`block.cc`table class: `Blocks`main.cc`table variable: `libc.so.1`hsearch.c`table
The output includes the name of the loadable object(s) where the program defines symbol, as well as the kind of entity each object is: class, function, or variable.
Because information from the dbx symbol table is read in as it is needed, the whereis command registers only occurrences of a symbol that are already loaded. As a debugging session gets longer, the list of occurrences can grow (see Debugging Information in Object Files and Executables).
For more information, see whereis Command.
