From 3c02bacf0f6bed54979e67d22c43745df9add4a0 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Wed, 31 Jul 2019 01:17:53 -0400 Subject: allow archs to define IPC_STAT, propagate time64 bit to other macros to make use of {sem,shm,msg}ctl IPC_STAT functionality to provide 64-bit time_t on 32-bit archs, IPC_STAT and related macros must be defined with bit 8 (0x100) set. allow archs to define IPC_STAT in bits/ipc.h, and define the other macros in terms of it so that they all get the same value of the time64 bit. --- include/sys/shm.h | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'include/sys/shm.h') diff --git a/include/sys/shm.h b/include/sys/shm.h index 8ef4e8f2..fd708cab 100644 --- a/include/sys/shm.h +++ b/include/sys/shm.h @@ -33,9 +33,9 @@ extern "C" { #define SHM_LOCK 11 #define SHM_UNLOCK 12 -#define SHM_STAT 13 +#define SHM_STAT (13 | (IPC_STAT & 0x100)) #define SHM_INFO 14 -#define SHM_STAT_ANY 15 +#define SHM_STAT_ANY (15 | (IPC_STAT & 0x100)) #define SHM_DEST 01000 #define SHM_LOCKED 02000 #define SHM_HUGETLB 04000 -- cgit v1.2.3-70-g09d2
