The values for various _POSIX_ constants are incorrect in <limits.h>. These constants must provide the most restrictive value for conforming implementations, not the actual implemented value: http://www.opengroup.org/onlinepubs/007908799/xsh/limits.h.html "Maximum Values "The symbolic constants in the following list are defined in <limits.h> with the values shown. These are symbolic names for the most restrictive value for certain features on a system supporting the Realtime Feature Group. A conforming implementation will provide values no larger than these values. A portable application will not require a smaller value for correct operation." >How-To-Repeat: >Fix: Index: limits.h =================================================================== RCS file: /space/mirror/ncvs/src/include/limits.h,v retrieving revision 1.16 diff -u -r1.16 limits.h --- limits.h 29 Apr 2003 13:35:58 -0000 1.16 +++ limits.h 24 Oct 2006 10:41:43 -0000 @@ -41,18 +41,18 @@ #if __POSIX_VISIBLE #define _POSIX_ARG_MAX 4096 -#define _POSIX_CHILD_MAX 25 +#define _POSIX_CHILD_MAX 6 #define _POSIX_LINK_MAX 8 #define _POSIX_MAX_CANON 255 #define _POSIX_MAX_INPUT 255 #define _POSIX_NAME_MAX 14 -#define _POSIX_NGROUPS_MAX 8 -#define _POSIX_OPEN_MAX 20 -#define _POSIX_PATH_MAX 256 +#define _POSIX_NGROUPS_MAX 0 +#define _POSIX_OPEN_MAX 16 +#define _POSIX_PATH_MAX 255 #define _POSIX_PIPE_BUF 512 #define _POSIX_SSIZE_MAX 32767 #define _POSIX_STREAM_MAX 8 -#define _POSIX_TZNAME_MAX 6 +#define _POSIX_TZNAME_MAX 3 #define BC_BASE_MAX 99 /* max ibase/obase values in bc(1) */ #define BC_DIM_MAX 2048 /* max array elements in bc(1) */ @@ -74,7 +74,7 @@ #endif #if __POSIX_VISIBLE >= 199309 -#define _POSIX_AIO_LISTIO_MAX 16 +#define _POSIX_AIO_LISTIO_MAX 2 #define _POSIX_AIO_MAX 1 #define _POSIX_DELAYTIMER_MAX 32 #define _POSIX_MQ_OPEN_MAX 8 >Release-Note: >Audit-Trail: >Unformatted:
