> That should be 7 + 11 - 1 = 17 and 7 + 6 - 1 = 12, shouldn't it? Yep, it should be. Misread my terminal output and wondered for a bit why the second one is longer than the first. Should have thought about double-checking.

From bccdc7d72cc1ea8a0d2aa04acf86e0afd2a3d6b5 Mon Sep 17 00:00:00 2001 From: Mingye Wang <[email protected]> Date: Wed, 21 Jun 2023 20:11:57 +0800 Subject: [PATCH] Make SIG2STR_MAX usable in #if The text accepted for POSIX issue 8 requires that SIG2STR_MAX be usable in #if, which we currently break with sizeof. Use static values instead. --- newlib/libc/include/sys/signal.h | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/newlib/libc/include/sys/signal.h b/newlib/libc/include/sys/signal.h index 8dc5fb9c34..96bf9781ae 100644 --- a/newlib/libc/include/sys/signal.h +++ b/newlib/libc/include/sys/signal.h @@ -245,9 +245,9 @@ int sigqueue (pid_t, int, const union sigval); /* POSIX Issue 8 adds sig2str() and str2sig() */ #if __SIZEOF_INT__ >= 4 -#define SIG2STR_MAX (sizeof("RTMAX+") + sizeof("4294967295") - 1) +#define SIG2STR_MAX 17 /* (sizeof("RTMAX+") + sizeof("4294967295") - 1) */ #else -#define SIG2STR_MAX (sizeof("RTMAX+") + sizeof("65535") - 1) +#define SIG2STR_MAX 12 /* (sizeof("RTMAX+") + sizeof("65535") - 1) */ #endif int sig2str(int, char *);
