System: NetBSD jacaranda.noi.kre.to 10.99.12 NetBSD 10.99.12 (JACARANDA:1.1-20250119) #172: Sun Jan 19 08:59:18 +07 2025 kre@jacaranda.noi.kre.to:/usr/obj/testing/kernels/amd64/JACARANDA amd64
Architecture: x86_64
Machine: amd64
>Description:
	wctomb.3 says:

	RETURN VALUES
	     positive      Number of bytes for the valid multibyte character pointed
			   to by s.  There are no cases that the value returned is
			   greater than n or the value of the MB_CUR_MAX macro.

	WTF is n ?    There is no 'n' in this function.   That sentence might have
	been cut&pasted from the man page for mbtowc(3) which does have an 'n' parameter.

>How-To-Repeat:
	RTFM.

>Fix:
	s/than n or//

	That exact substitution won't work because of markup.

 Module Name:	src
 Committed By:	riastradh

 Modified Files:
 	src/lib/libc/locale: wctomb.3

 Log Message:
 wctomb(3): Nix spurious reference to nonexistent parameter n.

 The return value is bounded by MB_CUR_MAX, that's all.  From C99,
 Sec. 7.20.7.3 `The wctomb function', paragraph 5, p. 323:

 > In no case will the return value be greater than the value of the
 > MB_CUR_MAX macro.
