From bb7fa1e9321e6469c0738c33f5e5bb8ac3d62067 Mon Sep 17 00:00:00 2001 From: Jim Meyering Date: Wed, 8 Oct 2008 10:44:12 +0200 Subject: maint: avoid warnings due to attribute warn_unused_result Now that a (void) cast no longer suffices to ignore warnings from gcc about uses of functions marked with the warn_unused_result attribute, we need an alternative. For the record, here's one of the ignorable warnings: "copy.c:233: warning: ignoring return value of 'fchown', declared with attribute warn_unused_result" * bootstrap.conf (gnulib_modules): Import ignore-value. * src/copy.c: Include "ignore-value.h". (set_owner): Use ignore_value in place of "(void)" casts, to ignore lchown and fchown failures. * src/cp.c (re_protect): Likewise, to ignore lchown failure. * src/remove.c (preprocess_dir): Remove unnecessary "(void)" cast. --- src/remove.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/remove.c') diff --git a/src/remove.c b/src/remove.c index 2e342c092..e92f78caf 100644 --- a/src/remove.c +++ b/src/remove.c @@ -1423,7 +1423,7 @@ preprocess_dir (DIR **dirp, struct rm_options const *x) for (size_t i = 0; i < n; i++) { /* ignore failure */ - (void) unlinkat (dir_fd, vv[i]->name, 0); + unlinkat (dir_fd, vv[i]->name, 0); } cleanup: -- cgit v1.2.3-54-g00ecf
