using std problem

Whenever i'm trying to use the std C header files
with the using statement
in a C++ project with Visual Studio i get an error at compile time
e.g.

Code:

---

...
#include <cstring>

using std::strlen;
...

...strlen( s )...

---

i want to use this type of using statement
so not to mess up a lot the namespace of my project.

the compile error says that the strlen() func is not a member
of the std namespace.
How could this be possible? Doesn't MS follow the C++ standard?

As you've probably guessed this is one the first times that i use
VS and i'd like to be the last also...

TIA

You are using VS 6.0,right?
IIRC in this VS release cstring,ctime and so on are not in the std namespace.
Try maybe this

Code:

---

namespace std
{
#include <cstring>
}

Not as closely as it should.

You can do what Wledge said, or just ignore the std:: prefix.

To make the code portable, try this:

Code:

---

#ifdef _MSC_VER
#if _MSC_VER < 1300
namespace std {
#endif
#endif

#include <cstring>
// and whatever things like ctime, etc, that don't have the std namespace in MSVC

#ifdef _MSC_VER
#if _MSC_VER < 1300
}
#endif
#endif

You're using Visual Studio 6 or earlier; that code would work fine on newer VC++ compilers. The main reason it's not standard is that your compiler is older than the standard itself.

The next version (.NET 2002) was 99% compliant with the standard, and the few discrepencies have been resolved for .NET 2003.

thanks for your answers
your solutions worked fine
it's obvious that I'm using VS 6.0

I've previously tried to use the __MSDOS__ predefined constant
but it didn't work. Any suggestions?
