+FUNCTION
+	<<wctrans>>---get wide-character translation type
+
+INDEX
+	wctrans
+
+ANSI_SYNOPSIS
+	#include <wctype.h>
+	wctrans_t wctrans(const char *<[c]>);
+
+TRAD_SYNOPSIS
+	#include <wctype.h>
+	wctrans_t wctrans(<[c]>)
+	const char * <[c]>;
+
+
+DESCRIPTION
+<<wctrans>> is a function which takes a string <[c]> and gives back
+the appropriate wctrans_t type value associated with the string,
+if one exists.  The following values are guaranteed to be recognized:
+"tolower" and "toupper".
+
+RETURNS
+<<wctrans>> returns 0 and sets <<errno>> to <<EINVAL>> if the
+given name is invalid.  Otherwise, it returns a valid non-zero wctrans_t
+value.
+
+PORTABILITY
+<<wctrans>> is C99.
+
+No supporting OS subroutines are required.
