From 6101eccc9f2a875f3702adccc3f3819059d5bffa Mon Sep 17 00:00:00 2001 From: Russell Bryant Date: Sun, 25 Jan 2009 02:49:30 +0000 Subject: [PATCH] Change ARRAY_LEN() to be more C++ safe. When the second part of this macro is written as 0[a] instead of a[0], it will force a failure if the macro is used on a C++ object that overloads the [] operator. git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@170943 65c4cc65-6c06-0410-ace0-fbb531ad65f3 --- include/asterisk/utils.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/include/asterisk/utils.h b/include/asterisk/utils.h index 941b5e57af..ee8bbd511d 100644 --- a/include/asterisk/utils.h +++ b/include/asterisk/utils.h @@ -657,7 +657,7 @@ void ast_enable_packet_fragmentation(int sock); */ int ast_mkdir(const char *path, int mode); -#define ARRAY_LEN(a) (sizeof(a) / sizeof(a[0])) +#define ARRAY_LEN(a) (sizeof(a) / sizeof(0[a])) #ifdef AST_DEVMODE #define ast_assert(a) _ast_assert(a, # a, __FILE__, __LINE__, __PRETTY_FUNCTION__)
