From: Rich Felker Date: Wed, 13 Apr 2011 20:45:43 +0000 (-0400) Subject: numerous fixes to sysv ipc X-Git-Tag: v0.7.9~58 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=07e865cc5afb11e6e882e998306ab0f7fb64357e;p=oweals%2Fmusl.git numerous fixes to sysv ipc some of these definitions were just plain wrong, others based on outdated ancient "non-64" versions of the kernel interface. as much as possible has now been moved out of bits/* these changes break abi (the old abi for these functions was wrong), but since they were not working anyway it can hardly matter. --- diff --git a/arch/i386/bits/ipc.h b/arch/i386/bits/ipc.h index 08316a37..51ad4427 100644 --- a/arch/i386/bits/ipc.h +++ b/arch/i386/bits/ipc.h @@ -1,25 +1,12 @@ -#define IPC_CREAT 01000 -#define IPC_EXCL 02000 -#define IPC_NOWAIT 04000 - -#define IPC_RMID 0 -#define IPC_SET 1 -#define IPC_STAT 2 -#ifdef _GNU_SOURCE -#define IPC_INFO 3 -#endif - -#define IPC_PRIVATE ((key_t) 0) - struct ipc_perm { - key_t key;
