From 03e334a1c7dc8c20c38902aa039440763acc9b17 Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Tue, 18 Mar 2014 19:22:43 +0100 Subject: util: replace close_nointr_nofail() by a more useful safe_close() safe_close() automatically becomes a NOP when a negative fd is passed, and returns -1 unconditionally. This makes it easy to write lines like this: fd = safe_close(fd); Which will close an fd if it is open, and reset the fd variable correctly. By making use of this new scheme we can drop a > 200 lines of code that was required to test for non-negative fds or to reset the closed fd variable afterwards. --- src/tmpfiles/tmpfiles.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'src/tmpfiles') diff --git a/src/tmpfiles/tmpfiles.c b/src/tmpfiles/tmpfiles.c index 74a01271e9..33e7cbc05d 100644 --- a/src/tmpfiles/tmpfiles.c +++ b/src/tmpfiles/tmpfiles.c @@ -496,7 +496,7 @@ static int write_one_file(Item *i, const char *path) { unescaped = cunescape(i->argument); if (unescaped == NULL) { - close_nointr_nofail(fd); + safe_close(fd); return log_oom(); } @@ -505,12 +505,12 @@ static int write_one_file(Item *i, const char *path) { if (n < 0 || (size_t) n < l) { log_error("Failed to write file %s: %s", path, n < 0 ? strerror(-n) : "Short write"); - close_nointr_nofail(fd); + safe_close(fd); return n < 0 ? n : -EIO; } } - close_nointr_nofail(fd); + safe_close(fd); if (stat(path, &st) < 0) { log_error("stat(%s) failed: %m", path); -- cgit v1.2.3-54-g00ecf
