towlower, towlower_l - transliterate upper-case wide characters to lower-case
#include <wctype.h> wint_t towlower(wint_t wc);
wint_t towlower_l(wint_t wc, locale_t loc);
The function towlower() is the wide character equivalent of the function tolower(3C). It converts the upper-case wide character wc to the equivalent lower-case wide character, if one exists. If one does not exist, it returns wc unchanged.
The function towlower_l() is equivalent to the function towlower(), but instead of operating in the current locale, operates in the locale specified by loc.
On successful completion, towlower() and towlower_l() return the lower-case character that corresponds to the argument passed. Otherwise, they return the argument unchanged.
No errors are defined.
