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(r) mapping
         "toupper" - realizes the toupper(r) 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 current locale.
