#[repr(C)]
pub struct CpuSet { /* private fields */ }
Expand description

CpuSet represents a bit-mask of CPUs.

CpuSets are used by sched_setaffinity and sched_getaffinity, for example.

Implementations§

source§

impl CpuSet

source

pub const MAX_CPU: usize = 1_024usize

field is the CPU id to add.

source

pub fn unset(&mut self, field: usize)

impl PartialEq for CpuSet

source§
