From dacd6cee76a08331b8c8616c5f30f70ee49aa2f9 Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Wed, 29 Jul 2015 20:31:07 +0200 Subject: tree-wide: port everything over to fflush_and_check() Some places invoked fflush() directly with their own manual error checking, let's unify all that by using fflush_and_check(). This also unifies the general error paths of fflush()+rename() file writers. --- src/login/logind-inhibit.c | 25 +++++++++++++++---------- 1 file changed, 15 insertions(+), 10 deletions(-) (limited to 'src/login/logind-inhibit.c') diff --git a/src/login/logind-inhibit.c b/src/login/logind-inhibit.c index 855c85402c..a261e6a719 100644 --- a/src/login/logind-inhibit.c +++ b/src/login/logind-inhibit.c @@ -86,11 +86,11 @@ int inhibitor_save(Inhibitor *i) { r = mkdir_safe_label("/run/systemd/inhibit", 0755, 0, 0); if (r < 0) - goto finish; + goto fail; r = fopen_temporary(i->state_file, &f, &temp_path); if (r < 0) - goto finish; + goto fail; fchmod(fileno(f), 0644); @@ -128,19 +128,24 @@ int inhibitor_save(Inhibitor *i) { if (i->fifo_path) fprintf(f, "FIFO=%s\n", i->fifo_path); - fflush(f); + r = fflush_and_check(f); + if (r < 0) + goto fail; - if (ferror(f) || rename(temp_path, i->state_file) < 0) { + if (rename(temp_path, i->state_file) < 0) { r = -errno; - unlink(i->state_file); - unlink(temp_path); + goto fail; } -finish: - if (r < 0) - log_error_errno(r, "Failed to save inhibit data %s: %m", i->state_file); + return 0; - return r; +fail: + (void) unlink(i->state_file); + + if (temp_path) + (void) unlink(temp_path); + + return log_error_errno(r, "Failed to save inhibit data %s: %m", i->state_file); } int inhibitor_start(Inhibitor *i) { -- cgit v1.2.3-54-g00ecf
