From aac4ad2c994742defc0623bd489206743241552c Mon Sep 17 00:00:00 2001 From: Peter Dufault Date: Sun, 8 Mar 1998 17:25:38 +0000 Subject: Reviewed by: bde Changes to support building with _POSIX_SOURCE set to 199309L: 1. Add sys/_posix.h to handle those preprocessor defs that POSIX says have effects when defined before including any header files; 2. Change POSIX4_VISIBLE back to _POSIX4_VISIBLE 3. Add _POSIX4_VISIBLE_HISTORICALLY for pre-existing BSD features now defined in POSIX. These show up when: _POSIX_SOURCE and _POSIX_C_SOURCE are not set or _POSIX_C_SOURCE is set >= 199309L and vanish when: _POSIX_SOURCE is set or _POSIX_C_SOURCE is < 199309L. 4. Explain these in man 9 posix4; 5. Include _posix.h and conditionalize on new feature test. --- include/limits.h | 14 ++++++++++---- 1 file changed, 10 insertions(+), 4 deletions(-) (limited to 'include/limits.h') diff --git a/include/limits.h b/include/limits.h index df120e6beb12..383c5cda087f 100644 --- a/include/limits.h +++ b/include/limits.h @@ -31,11 +31,12 @@ * SUCH DAMAGE. * * @(#)limits.h 8.2 (Berkeley) 1/4/94 - * $Id: limits.h,v 1.5 1997/12/27 22:56:41 steve Exp $ + * $Id: limits.h,v 1.6 1998/03/04 10:23:24 dufault Exp $ */ #ifndef _LIMITS_H_ #define _LIMITS_H_ +#include #ifndef _ANSI_SOURCE #define _POSIX_ARG_MAX 4096 @@ -61,14 +62,15 @@ #define _POSIX2_LINE_MAX 2048 #define _POSIX2_RE_DUP_MAX 255 -#ifdef POSIX4_VISIBLE -#define _POSIX_AIO_LISTIO_MAX 2 +#ifdef _POSIX4_VISIBLE + +#define _POSIX_AIO_LISTIO_MAX 16 #define _POSIX_AIO_MAX 1 #define _POSIX_DELAYTIMER_MAX 32 #define _POSIX_MQ_OPEN_MAX 8 #define _POSIX_MQ_PRIO_MAX 32 -#define _POSIX_RTSIG_MAX 8 +#define _POSIX_RTSIG_MAX 0 #define _POSIX_SEM_NSEMS_MAX 256 #define _POSIX_SEM_VALUE_MAX 32767 #define _POSIX_SIGQUEUE_MAX 32 @@ -76,6 +78,10 @@ #endif +#ifdef _POSIX4_VISIBLE_HISTORICALLY +#define AIO_LISTIO_MAX 16 +#endif + #endif /* !_ANSI_SOURCE */ #if !defined(_ANSI_SOURCE) && !defined(_POSIX_SOURCE) || defined(_XOPEN_SOURCE) -- cgit v1.2.3
