Function sched_setaffinity

pub fn sched_setaffinity(pid: Pid, cpuset: &CpuSet) -> Result<()>

sched_setaffinity set a thread’s CPU affinity mask (sched_setaffinity(2))

pid is the thread ID to update. If pid is zero, then the calling thread is updated.

The cpuset argument specifies the set of CPUs on which the thread will be eligible to run.

Example

Binding the current thread to CPU 0 can be done as follows:

use nix::sched::{CpuSet, sched_setaffinity};
use nix::unistd::Pid;

let mut cpu_set = CpuSet::new();
cpu_set.set(0).unwrap();
sched_setaffinity(Pid::from_raw(0), &cpu_set).unwrap();
