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.
