From 89d3df6e5420878e35a93a481105017a94a02852 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Sun, 3 Feb 2013 16:09:05 -0500 Subject: [PATCH] streamline old-kernel fallback path of pipe2 to use syscalls directly also, don't waste code/time on F_GETFL since pipes always have blank flags initially (at least on old kernels, which are all this fallback code matters for). --- src/unistd/pipe2.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/src/unistd/pipe2.c b/src/unistd/pipe2.c index 973e8ec3..bbeabcbf 100644 --- a/src/unistd/pipe2.c +++ b/src/unistd/pipe2.c @@ -11,12 +11,12 @@ int pipe2(int fd[2], int flag) ret = __syscall(SYS_pipe, fd); if (ret) return __syscall_ret(ret); if (flag & O_CLOEXEC) { - fcntl(fd[0], F_SETFD, FD_CLOEXEC); - fcntl(fd[1], F_SETFD, FD_CLOEXEC); + __syscall(SYS_fcntl, fd[0], F_SETFD, FD_CLOEXEC); + __syscall(SYS_fcntl, fd[1], F_SETFD, FD_CLOEXEC); } if (flag & O_NONBLOCK) { - fcntl(fd[0], F_SETFL, fcntl(fd[0], F_GETFL) | O_NONBLOCK); - fcntl(fd[1], F_SETFL, fcntl(fd[1], F_GETFL) | O_NONBLOCK); + __syscall(SYS_fcntl, fd[0], F_SETFL, O_NONBLOCK); + __syscall(SYS_fcntl, fd[1], F_SETFL, O_NONBLOCK); } return 0; } -- 2.25.1
