Yes. However the definition she suspects that has the bug:


bool UserList::DeleteUser(const char *pNick)
{
    bool bRet = false;
 
    if(m_mapUsers.size() > 0)
    {
        UserMap::iterator it = m_mapUsers.find(pNick);
        if(it != m_mapUsers.end())
        {
            m_mapUsers.erase(it);
            bRet = true;
        }
    }
 
    return bRet;
}


As I said it is OK. 


However the member functions

void AddUser(User *pUser);
User *FindUser(const char *pNick);

are a different story (I included in this list the DeleteUser() from
rashness).
