std::regex_traits<CharT>::translate_nocase

CharT translate_nocase( CharT c ) const;

Obtains the comparison key for the character c

When the regex library needs to match two characters c1 and c2 and the flag std::regex_constants::icase is true, it executes regex_traits<> :: translate_nocase (c1) == regex_traits<> :: translate_nocase (c2)

Standard library specializations of std::regex_traits return std::use_facet < std::ctype <CharT>> (getloc( ) ).tolower (c) , that is, convert c

Parameters

c

-

character that needs to be examined for equivalence, ignoring case
