Q: The attribute [[deprecated]] C++ 14 Feature

1 Answer

Jan 4

The deprecated attribute allows marking an entity deprecated, which makes it still legal to use but puts users on notice that use is discouraged and may cause a warning message to be printed during compilation. An optional string literal can appear as the argument of deprecated, to explain the rationale for deprecation and/or to suggest a replacement.

[[deprecated]] int f();

[[deprecated("g() is thread-unsafe. Use h() instead")]]
void g( int& x );

void h( int& x );

void test()
{
  int a = f(); // warning: 'f' is deprecated
  g(a); // warning: 'g' is deprecated: g() is thread-unsafe. Use h() instead
}
