From 2f897e72580eb68526972caf3ef815c5be50daba Mon Sep 17 00:00:00 2001 From: Paul Eggert Date: Mon, 26 Sep 2005 23:02:14 +0000 Subject: (touch): Handle "touch -c - >&-" by checking for EBADF and ENOSYS. Do not pass "-" to futimens; pass NULL instead. If close (STDIN_FILENO) fails, report the error separately instead of letting the 'close' pollute errno. --- src/touch.c | 20 +++++++++++++++++--- 1 file changed, 17 insertions(+), 3 deletions(-) (limited to 'src/touch.c') diff --git a/src/touch.c b/src/touch.c index 870606123..06c9646bc 100644 --- a/src/touch.c +++ b/src/touch.c @@ -154,7 +154,7 @@ touch (const char *file) error (0, open_errno, _("creating %s"), quote (file)); else { - if (no_create && errno == ENOENT) + if (no_create && (errno == ENOENT || errno == EBADF)) return true; error (0, errno, _("failed to get attributes of %s"), quote (file)); @@ -182,9 +182,23 @@ touch (const char *file) t = timespec; } - ok = (futimens (fd, file, t) == 0); + ok = (futimens (fd, (fd == STDOUT_FILENO ?
