Why vim not search STL headers?

In vim it is common to open a header in place, which is really a handy feature for browsing a directory hierarchy.

But you might find this functionality seems to fail with C++ STL headers : when the cursor is blinking under "#include <iostream>", say, and your hitting 'gf' will not respond by entering that header but engender a grouch like following instead:

"E447: Can't find file iostream in path".

In actuality it is quite easy to resolve this problem by riffling through vim manual.

Treatment:

open the rc file of vim, for instance, /etc/vimrc, add following setting :

set path = **,/usr/include/c++/**

provided your c++ STL headers are hoarded in /usr/include/c++.

reopen the source code you were previously browsing around and try "gf" again, it should work now! It is really that piece of cake!  Really extensible is vim!
