The type wchar_t is a distinct type rather than a typedef to an
existing integral type[.](#1.sentence-1)

The token wchar_t is a keyword in C++ ([[lex.key]](lex.key "5.12 Keywords"))[.](#1.sentence-2)

It does not appear as a macro or type name defined in any of[<cstddef>](cstddef.syn#header:%3ccstddef%3e "17.2.1 Header <cstddef> synopsis [cstddef.syn]"),[<cstdlib>](cstdlib.syn#header:%3ccstdlib%3e "17.2.2 Header <cstdlib> synopsis [cstdlib.syn]"),
or [<cwchar>](cwchar.syn#header:%3ccwchar%3e "28.7.3 Header <cwchar> synopsis [cwchar.syn]")[.](#1.sentence-3)
