From 725c55528dff9eefbc88a943749f3bc89bcb433f Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Thu, 31 Jan 2013 00:49:53 -0500 Subject: SOL_TCP is nonstandard and not in the reserved namespace alternatively, we could define it in sys/socket.h since SO* is reserved there, and tcp.h includes sys/socket.h in extensions mode. note that SOL_TCP is simply wrong and it's only here for compatibility with broken applications. the correct argument to pass for setting TCP socket options is IPPROTO_TCP, which of course has the same value as SOL_TCP but works everywhere. --- include/netinet/tcp.h | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) (limited to 'include') diff --git a/include/netinet/tcp.h b/include/netinet/tcp.h index 94e54cf3..f0fc1259 100644 --- a/include/netinet/tcp.h +++ b/include/netinet/tcp.h @@ -18,9 +18,8 @@ #define TCP_CONGESTION 13 #define TCP_MD5SIG 14 -#define SOL_TCP 6 - #if defined(_GNU_SOURCE) || defined(_BSD_SOURCE) +#define SOL_TCP 6 #include #include #endif -- cgit v1.2.1
