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(3) 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
       C99.


NOTES
       The behavior of wctrans() depends on the LC_CTYPE category of the current locale.
