Name conflict with standard library

Question

My project uses a third party modules where one of the header file has defined 'errc'

typedef int             errc;

I want to use STL in project but when I add stl header file I get name conflict for errc since its class name in the standard library.

error C2872: 'errc' : ambiguous symbol

I don't really want to change the third party module, is there any way I can come around this problem and work with the standard library in the project?

The only thing you should have to change is delete `using namespace std;` from your files. — Praetorian, Nov 08 '12 at 16:07
yea but poor design/naming by third party module, they have used it which is outside my control — zar, Nov 08 '12 at 16:08
@Praetorian so I have to use fully qualified names than for stl objects! — zar, Nov 08 '12 at 16:09
@zadane, [That's a good thing.](http://stackoverflow.com/questions/1452721/why-is-using-namespace-std-considered-a-bad-practice-in-c) The using statements are scoped as well. — chris, Nov 08 '12 at 16:09
@zadane: the `std` namespace is there for a reason, and you just found out what that reason is. (You can use selective `using` statements to cut down on the typing.) — Fred Foo, Nov 08 '12 at 16:14
Zadane: without changing anything else, try writing std::errc and ::errc in your program and see if that clears up the ambiguity. — David Grayson, Nov 08 '12 at 16:14

Don't use in the file

using namespace std;

But you can still include it into functions, say

void f()
{
  using namespace std;

  cout<<endl;
}
