<cwchar> <cwctype>


Wide End-of-File
Macro constant definition that expands to a constant expression of type wint_t whose value does not correspond to any character of the extended character set.

It is used as the value returned by several wide character functions to indicate either that the End-of-File has been reached, or to indicate a character value not corresponding to any member of the extended character set.

This macro is also defined in header <cwchar>.
