From ccc7b4c3a17ade90de71e1e0f44deebbffd646e6 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Tue, 26 Mar 2013 23:07:31 -0400 Subject: remove __SYSCALL_SSLEN arch macro in favor of using public _NSIG the issue at hand is that many syscalls require as an argument the kernel-ABI size of sigset_t, intended to allow the kernel to switch to a larger sigset_t in the future. previously, each arch was defining this size in syscall_arch.h, which was redundant with the definition of _NSIG in bits/signal.h. as it's used in some not-quite-portable application code as well, _NSIG is much more likely to be recognized and understood immediately by someone reading the code, and it's also shorter and less cluttered. note that _NSIG is actually 65/129, not 64/128, but the division takes care of throwing away the off-by-one part. --- src/signal/sigpending.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/signal/sigpending.c') diff --git a/src/signal/sigpending.c b/src/signal/sigpending.c index 46ce3036..3d193df8 100644 --- a/src/signal/sigpending.c +++ b/src/signal/sigpending.c @@ -3,5 +3,5 @@ int sigpending(sigset_t *set) { - return syscall(SYS_rt_sigpending, set, __SYSCALL_SSLEN); + return syscall(SYS_rt_sigpending, set, _NSIG/8); } -- cgit v1.2.1
