test_rw_locks shows how to use ACE_Local_RLock, ACE_Local_WLock,
ACE_Remote_RLock, and ACE_Remote_WLock.
Here are the options to test_rw_locks:
% ./test_rw_lock -u
-i ignore deadlock
-n <iterations>
-r <reads>
-d debug
-s sleep during writes
-t <threads>
test_rw_locks spawns <threads> number of threads which perform the
following algorithm:
for <iterations>
{
for <reads>
acquire read lock
for <reads>
release read lock
acquire write lock
if (sleep during writes)
sleep for 1 second
release write lock
}
The output should show that multiple readers can acquire the lock for
reading simultaneously (note that this also tests recursive
acquisition.) When a writer lock is acquired, the output should show
that no thread holds a reader lock.
To run a test, simply type:
% ./test_rw_lock
This should show output as described above.
