NAME
       towctrans - wide-character transliteration

SYNOPSIS
       #include <wctype.h>

       wint_t towctrans(wint_t wc, wctrans_t desc);

DESCRIPTION
       The  towctrans() function shall transliterate the wide-character code wc using the mapping
       described by desc. The current setting of the LC_CTYPE category should be the same as dur-
       ing the call to wctrans() that returned the value desc.	  If the value of desc is invalid
       (that is, not obtained by a call to wctrans() or desc is invalidated by a subsequent  call
       to setlocale() that has affected category LC_CTYPE ), the result is unspecified.

       An  application wishing to check for error situations should set errno to 0 before calling
       towctrans(). If errno is non-zero on return, an error has occurred.

RETURN VALUE
       If successful, the towctrans() function shall return the mapped value of wc using the map-
       ping described by desc. Otherwise, it shall return wc unchanged.

ERRORS
       The towctrans() function may fail if:

       EINVAL desc contains an invalid transliteration descriptor.

       The following sections are informative.

EXAMPLES
       None.

APPLICATION USAGE
       The  strings  "tolower"	and "toupper" are reserved for the standard mapping names. In the
       table below, the functions in the left column are equivalent to the functions in the right
       column.

	      towlower(wc)    towctrans(wc, wctrans("tolower"))
	      towupper(wc)    towctrans(wc, wctrans("toupper"))
