Returning a pointer (as others have commented on) is a valid method. The
method I use for this, however, is to throw, since I want to return a
reference.

CPlayer& FindPlayer( const std::string Name )
{
    for ( map_player::iterator i = World.ConnectedPlayers.begin(); i !=
World.ConnectedPlayers.end(); ++i)
    {
        if ( (*i).second.Character.Name == Name )
            return (*i).second;
    }

    throw 0;

}

//////////////////

   try
   {
       CPlayer& TargetPlayer = FindPlayer( Name );
       PlayerMoveTo( TargetPlayer, ThisPlayer.Character.Map,
ThisPlayer.Character.Pos );
       SendMessageToPlayer( Socket, MSG_SERVER_MESSAGE, Name + "
summoned." );
   }
   catch ( int )
   {
       SendMessageToPlayer( Socket, MSG_SERVER_MESSAGE, Name + " not
found." );
   }


next time, don't be so cheap and use an exception class instead of an
ordinary int (which does not hold any error info)
