Still new to QNX and could not find the answer in docum:

Suppose there is a resource manager that is an i/o server, device driver, etc.
It is called by various clients running at various priorities. 
Does QNX provide automatic "priority inheritance" in the meaning that the server gets a priority increment when a high 
priority client is waiting?

If not, what is the best practice to set the server priority? Just set it "high enough" ?

Thanks for any idea,
