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.
