// 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...
