NAME
       wctrans - wide character translation mapping

SYNOPSIS
       #include <wctype.h>

       wctrans_t wctrans(const char *name);

DESCRIPTION
       The  wctrans_t type represents a mapping which can map a wide character
       to another wide character. Its nature is implementation dependent,  but
       the  special  value  (wctrans_t)0  denotes  an invalid mapping. Nonzero
       wctrans_t values can be passed to the towctrans  function  to  actually
       perform the wide character mapping.

       The  wctrans  function returns a mapping, given by its name. The set of
       valid names depends on the LC_CTYPE category of the current locale, but
       the following names are valid in all locales.
         "tolower" - realizes the tolower(3) mapping
         "toupper" - realizes the toupper(3) mapping

RETURN VALUE
       The wctrans function returns a mapping descriptor if the name is valid.
       Otherwise it returns (wctrans_t)0.

CONFORMING TO
       ISO/ANSI C, UNIX98

NOTES
       The behaviour of wctrans depends on the LC_CTYPE category of  the  cur-
       rent locale.
