Re: Question about STL containers in multithreaded environment

so the good way is:

const iteraror=map.find(key);
if(iterator!=map.end())
return iterator->second;
or also I have to make a const alias to map also ??

All STL containers is allowed (but it is not obligatory) to have
reference counted implementation to optimize copying and swaping
operations (especially for std::string-s). So one cannot guarantee that
if you invoke non-const method you container will not be changed. You
has to make const alias in your case also.
