Just my mystery is as follow:
Windows 1:
% ./test_fcntl
My pid: 43490
Windows 2:
% ls -l /tmp/lockfile
-r-sr-x--- 1 daichi wheel 0 10月 5 15:02 /tmp/lockfile <--- is it weird, isn't it?
% ./test_fcntl
test_fcntl: open: Permission denied
%
Oops... What's wrong... /tmp is as follow:
% mount | grep tmp
/dev/ada0s1f on /tmp (ufs, local, noatime, soft-updates)
% dumpfs /tmp | grep journal
flags soft-updates+journal
%
And working scene:
Windows 2:
% chmod u+w /tmp/lockfile
% ls -l /tmp/lockfile
-rwsr-x--- 1 daichi wheel 0 10月 5 15:22 /tmp/lockfile
% ./test_fcntl
My pid: 43646
test_fcntl: fcntl[1]: Resource temporarily unavailable
PID=43490 has the lock
