Control Task #2 from Task #1

Hi,

How can I enable a Nuttx task (task #1) to control another Nuttx task (task #2)? In FreeRTOS, I was able to use task_suspend(task_handle of task #2) and task_resume(task_handle of task #2) from task #1 to control task #2.

How can I best do this in Nuttx?

Best,

Thank you, Tim! 
I also found an example here:

Is there any example I can look at?
