Note that if `t_TP` is both const‐ and volatile‐qualified, it will not match `volatile t_TP&`, hence the need for the const overloads. == Synopsis Declared in `<bslmf_invokeresult.h>` [source,cpp,subs="verbatim,replacements,macros,-callouts"] ---- template<class t_TP> static xref:BloombergLP/bslmf/Tag-0b.adoc[bslmf::Tag<false>] checkVolatile(t_TP&); ---- [.small]#Created with https://www.mrdocs.com[MrDocs]#
