API usage example
This example shows how to use timed operations.
First of, run make to build this example.
To start the example run ./init.
When you are done run ./cleanup.
Running instances of ./poll will wait for new messages
continuously, but with one second timeouts.
./slow-poll works like ./poll, except it will sleep
for one second every time it receives a message.
Running instances of ./read will read for ten seconds
and then time out.
./poll, ./read, and ./slow-poll will stop if the message
"stop" is broadcasted.
./write will wait for atmost a tenth of a seconds before
failing. This means that if two instances of ./write is
started at the same time one of them will fail if
./slow-poll is running.
./poll, ./read, ./init and ./cleanup are run without any
additional arguments. ./write is run with the message
as the second argument.
