auto pointer in c++

Question

I am curious to know how an auto_ptr is implemented in c++. And i tried to find out where the source of it is located in ubuntu 10.04. I could only find the .h file but couldn't find its implementation. where can i find it?

Answer 1

The .h file is almost certainly its implementation. auto_ptr is a template. Since template implementations need to be included in full, they're normally in the .h files.

Answer 2

The auto_ptr is a template, and the whole code is most likely in the header file.

You can check on libstdc++ 4.4 implementation here.
