list of pointers in c++

What i want to do is

for (list<cPacket *>::iterator i = cache.begin(); i != cache.end(); i++){
        if( strcmp(i->getName(),id) == 0 ){
            return true;
        }
}

where getName is function of the class cPacket, But it does not work, i tries also i.operator->()->getName(), and again nothing.

Can anybody help me?

replace 

list<cPacket *>::iterator i

with 

list<cPacket>*::iterator i

*i dereferences the iterator. As the data type of the list is pointer to cPacket, you need to apply the -> operator to access its members. Parentheses are needed for proper precendence:

(*i)->whatever()

(*i)->getName()

is what you are looking for.
