The sgi STL site is very good. Here is the entry for std::map
"http://www.sgi.com/tech/stl/Map.html";
The iterators in a std::map point to std::pair<> s of <key,data>, so
you can use the std::pair::first and std::pair::second to access the
keys and data elements.
The iterator can be used like so:
typedef std::map< int, playerclass* > PlayerMap;
PlayerMap playerMap;
PlayerMap::iterator it = playerMap.begin();
while( it != playerMap.end() )
{
int i = it->first;
playerclass *player = it->second;
}

Im using a map to represent a list of players, but I have found a
problem I cant solve using the basic STL reference. I need to iterate
through the whole list
Supposing the list is defined as map<int,*playerclass> what is the
correct way to get the data or the key from iterator?
