Maybe. But he's also saying that you should start by reading the user manual first. You cannot expect your program to function according to your expectations if it contains fundamental errors! At this moment there is little point in asking more questions; fix the glaring errors, come back when it is up and running.
Programs - whether RTOS or not - neither know nor care anything of your expectations.
Programs function according to the specifications given in the relevant Documentation.
It is up to you to study the Documentation, and base your expectations on what you find there.
