+FUNCTION
+	<<wcslen>>---get wide-character string length 
+
+ANSI_SYNOPSIS

+	size_t wcslen(const wchar_t *<[s]>);
+
+TRAD_SYNOPSIS
+	size_t wcslen(<[s]>
+	const wchar_t *<[s]>;
+
+DESCRIPTION
+	The <<wcslen>> function computes the number of wide-character codes
+	in the wide-character string to which <[s]> points, not including the
+	terminating null wide-character code.
+
+RETURNS
+	The <<wcslen>> function returns the length of <[s]>; no return value is
+	reserved to indicate an error.
