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.
