Iterator compile error
Hi I am getting a compile error in the assignment.
It is complaining about cannot convert 'const std::pair<const int, void(*)()> to void(*)()
What could be wrong here.

typedef void (*Callback)();
typedef std::map<int, Callback> listenerMap_t;
typedef std::map<int, Callback>::const_iterator listenerIter_t;
Callback cb;
listenerIter_t listenerIter = listenerMap.find(attr);
if(listenerIter != listenerMap.end() )
{
cb = *listenerIter; <--- error

Hi evlrix,
Why it has to be ->second ?( I admit I am not very familar with STD. I am still learning). Thx.

That was my fault in your last Q - 'find()' returns a 'pair', thus you need 'second' here. Full credit to evilrix for spotting that, no points for this comment please ;o)
