For now ,I just search "*" in token's m_Type ,it is not easy to do this for current parser. :D

Hi, can you explain this sentence? I can't fully understand you. Thanks.

BTW:My lab's networking was broken, so, I can't test this patch these days till the networking was fixed. :(

Not understood it fully too. :wink:

killerbot:
well in C++0x there will be several cases where you no longer will have to specify the type of a variable, the compiler will determine it for you.

Examples :
auto Count = 10;  // --> int

std::vector<std::string> Hello;

for(auto It = Hello.cbegin(); It != Hello.cend(); ++It)
{
  std::cout << *It; // -> std::vector<std::string>const_iterator
}

this last loop can also be written with the new foreach, and also there the compiler will deduce the type.

And so will code completion parsers have to deduce this according to the new language rules.
