We call a method called 'connect' of the instance 'client'.
client.connect(host, httpPort) will return a value, if it is ZERO - indicate that it is failed by the one who programmed it, code in the block will run.

Bad code practice though, IMO

Just curious; why is the above a bad practice? It's common in alot of languages for a function to return true on success, false on failure.

He probably wants you to use exceptions. In most cases that is preferrable, but not always.

Then we get into the argument: is not connecting actually an exceptional condition (deserving of a try/catch and exception handling) or is not connecting a normal operating condition to be handled by some retries and after that we truly have an exception...

Also, this is a $4 wifi chip, not a multi-core commercial server. I'm just happy we're not writing assembly language.
