What do you mean by ‘publish a message’?

You can have the receiving task waiting for a message in a Queue, MessageBuffer, Semaphore, or using Direct-to-Task notifications (amoung other options), and another task signal it with that item.

Thanks Richard Damon for your reply.

Actually I would like to do Inter-task communication between two tasks. I have two tasks one is uart task and another one is watch task.

I would like to initilize the watch task events by posting a message from uart task

Again, you are using some loosly defined terms, like ‘initialize the watch task events’. What exactly are you wanting to do. I mentioned a number of the tool that FreeRTOS privides to do inter-task (or interrupt-to-task) communication.
