[Dev-C++] Reverse Map lookup.

[David M. <ci...@ya...>]

Ok, here is a question for all you STL users out there.

I have a map which uses a string as the key and the data
object is a function pointer (I am yet to implement this so
don't ask me how I did it). What I would need (please don't
ask me why, it is the request of another member of our
team) but I also need to do a reverse-lookup (for a given
function pointer address what strings are assigned).

For the curious this is for a dynamic command system. When
the user enters a command we look up what function is
assigned to that command. For now you can assume that it is
a 1:1 relationship, no more than one command is mapped to a
particular function. This might change in the future
(should we start implementing aliases) so a solution that
would solve this as well would be quite helpful.

So far the only solutions I see is to set up 2 maps (2nd
one for the reverse lookup would have to be a multimap if
more than one command can be mapped to a particular
function). To make sure everything is kept in sync I would
probably have to encapsulate it and over-ride some
operators.

Thanks in advance
