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 current locale.
