| 31 | The class template <a class="link" href="../reference/function_traits.html" title="function_traits">function_traits</a> | |
| 32 | extracts information from function types (see also <a class="link" href="../reference/is_function.html" title="is_function">is_function</a>). | |
| 33 | This traits class allows you to tell how many arguments a function takes, | |
| 34 | what those argument types are, and what the return type is. | |
