:relfileprefix: ../../
:mrdocs:

This `struct` template implements a meta‐function to determine if the (template parameter) `t_TYPE` is the (possibly cv‐qualified) `void` type. This `struct` derives from `bsl::true_type` if `t_TYPE` is the `void` type, and `bsl::false_type` otherwise.

== Synopsis

Declared in `<bslmf_isvoid.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
template<class t_TYPE>
struct IsVoid
    : bsl::is_void<t_TYPE>::type
----

== Description

Note that although this `struct` is functionally equivalent to `bsl::is_void`, and the use of `bsl::is_void` should be preferred.
