wctrans(3)

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.

   current locale.
