If you have ddb you can use code like this (from i386 stack trace code):
sym = db_search_symbol(eip, DB_STGY_ANY, &offset);
db_symbol_values(sym, &name, NULL);
Where eip is the function pointer. You then have the name of the function
in name. You can also invoke stack traces by calling db_stack_trace_cmd()
with the right arguments.
