towctrans(3C)            Standard C Library Functions            towctrans(3C)

NAME
       towctrans, towctrans_l - wide-character mapping

SYNOPSIS
       #include <wctype.h>

       wint_t towctrans(wint_t wc, wctrans_t desc);
       wint_t towctrans_l(wint_t wc, wctrans_t desc, locale_t locale);

DESCRIPTION
       The towctrans() and towctrans_l functions map the wide character wc us‐
       ing the mapping described by desc. The setting of the LC_CTYPE category
       in  the current locale, or in the locale represented by locale, respec‐
       tively, should be the same as during  the  call  to  wctrans()  or  wc‐
       trans_l() that returned the value desc.


       If  the  value of desc is invalid, the result is unspecified. For towc‐
       trans(), desc is invalid if it was not obtained by a call to wctrans(),
       or if desc is invalidated by a subsequent call to setlocale() that  has
       affected  category LC_CTYPE. For towctrans_l, desc is invalid if it was
       not obtained by a call to wctrans_l() with the same  locale  object  as
       locale.


       The function call towctrans(wc, wctrans("tolower")) behaves the same as
       towlower(wc).


       The function call towctrans_l(wc, wctrans_l("toupper", locale), locale)
       behaves the same as towupper_l(wc, locale).

RETURN VALUES
       The  towctrans() and towctrans_l() functions return the mapped value of
       wc, using the mapping described by desc; otherwise, they return wc  un‐
       changed.
