NAME
       wctrans - define character mapping

SYNOPSIS
       #include <wctype.h>

       wctrans_t wctrans(const char *charclass);

DESCRIPTION
       The wctrans() function is defined for valid character mapping names identified in the current locale. The charclass is a string identifying
       a generic character mapping name for which codeset-specific information is required.  The following character mapping names are defined	in
       all locales - "tolower" and "toupper".

       The  function  returns  a  value  of  type  wctrans_t,  which  can be used as the second argument to subsequent calls of towctrans(3C). The
       wctrans() function determines values of wctrans_t according to the rules of the coded character set defined by character  mapping  informa-
       tion  in  the  program's locale (category LC_CTYPE). The values returned by wctrans() are valid until a call to setlocale(3C) that modifies
       the category LC_CTYPE.

RETURN VALUES
       The wctrans() function returns 0 if the given character mapping name is not valid for the current locale (category LC_CTYPE), otherwise	it
       returns a non-zero object of type wctrans_t that can be used in calls to towctrans(3C).

ERRORS
       The wctrans() function may fail if:

       EINVAL	       The character mapping name pointed to by charclass is not valid in the current locale.
