+FUNCTION
+	<<towctrans>>---extensible wide-character case mapping
+
+INDEX
+	towctrans
+
+ANSI_SYNOPSIS
+	#include <wctype.h>
+	wint_t towctrans(wint_t <[c]>, wctrans_t <[w]>);
+
+TRAD_SYNOPSIS
+	#include <wctype.h>
+	wint_t towctrans(<[c]>, <[w]>)
+	wint_t <[c]>;
+	wctrans_t <[w]>;
+
+
+DESCRIPTION
+<<towctrans>> is a function which converts wide-characters based on
+a specified translation type <[w]>.  If the translation type is
+invalid or cannot be applied to the current character, no change
+to the character is made.
+
+RETURNS
+<<towctrans>> returns the translated equivalent of <[c]> when it is a
+valid for the given translation, otherwise, it returns the input character.
+When the translation type is invalid, <<errno>> is set <<EINVAL>>.
+
+PORTABILITY
+<<towctrans>> is C99.
+
+No supporting OS subroutines are required.
