Sets thread’s priority and schedule policy

• May require privileges

Usage

Setting thread priority to minimum with normal schedule policy:

use thread_priority::*;

let thread_id = thread_native_id();
assert!(set_thread_priority_and_policy(thread_id,
                                       ThreadPriority::Min,
                                       ThreadSchedulePolicy::Realtime(RealtimeThreadSchedulePolicy::Fifo)).is_ok());

Note

In case the value is specified as ThreadPriority::Crossplatform and is incompatible with the policy, an error is returned. However if ThreadPriority::Min or ThreadPriority::Max are used, the correct value is used automatically according to the range of the policy’s allowed values.
