using void_t = typename make_void<Ts...>::type;
__type The type `void` for all `T`.
__header ` #include <boost/type_traits/make_void.hpp>` or ` #include <boost/type_traits.hpp>`
[table Examples
[[Expression] [Result Type]]
[[`make_void<int>::type`][`void`]]
[[`make_void<int&>::type`] [`void`]]
[[`make_void<int(*)(int)>::type`] [`void`]]
[[`make_void<int[]>::type`] [`void`]]
[[`make_void<int[1]>::type`] [`void`]]
[[`make_void<>::type`] [`void`]]
[[`make_void<int, int>::type`] [`void`]]
]
[all_compilers] However, the type alias `void_t` is only available if the compiler supports template aliases.
Further, in the absence of variadic-template support, `make_void` only supports up to 5 parameters.
