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.
