From 3b9a1d87cc468cfcd6f9ddfd98ac389fa5840f10 Mon Sep 17 00:00:00 2001 From: Alexander Kuleshov Date: Sat, 2 Jul 2016 23:38:47 +0600 Subject: basic/fd-util: introduce stdio_unset_cloexec() function There are some places in the systemd which are use the same pattern: fd_cloexec(STDIN_FILENO, false); fd_cloexec(STDOUT_FILENO, false); fd_cloexec(STDERR_FILENO, false); to unset CLOEXEC for standard file descriptors. This patch introduces the stdio_unset_cloexec() function to hide this and make code cleaner. --- src/basic/fd-util.c | 6 ++++++ src/basic/fd-util.h | 1 + 2 files changed, 7 insertions(+) (limited to 'src') diff --git a/src/basic/fd-util.c b/src/basic/fd-util.c index 8b466cff15..5c820332a5 100644 --- a/src/basic/fd-util.c +++ b/src/basic/fd-util.c @@ -186,6 +186,12 @@ int fd_cloexec(int fd, bool cloexec) { return 0; } +void stdio_unset_cloexec(void) { + fd_cloexec(STDIN_FILENO, false); + fd_cloexec(STDOUT_FILENO, false); + fd_cloexec(STDERR_FILENO, false); +} + _pure_ static bool fd_in_set(int fd, const int fdset[], unsigned n_fdset) { unsigned i; diff --git a/src/basic/fd-util.h b/src/basic/fd-util.h index b86e41698a..34b98d4aec 100644 --- a/src/basic/fd-util.h +++ b/src/basic/fd-util.h @@ -63,6 +63,7 @@ DEFINE_TRIVIAL_CLEANUP_FUNC(DIR*, closedir); int fd_nonblock(int fd, bool nonblock); int fd_cloexec(int fd, bool cloexec); +void stdio_unset_cloexec(void); int close_all_fds(const int except[], unsigned n_except); -- cgit v1.2.3-54-g00ecf
