- // TITLE: std:: namespace for C API's
- // DESCRIPTION: The contents of C++ standard headers for C library
- // functions (the <c...> headers) have not been placed
- // in namespace std. This test is difficult - some libraries
- // "fake" the std C functions by adding using declarations
- // to import them into namespace std, unfortunately they don't
- // necessarily catch all of them...
