Function nc::sched_setparam
source · pub unsafe fn sched_setparam(
pid: pid_t,
param: &sched_param_t
) -> Result<(), Errno>
Expand description
Set scheduling paramters.
§Example
// This call always returns error because default scheduler is SCHED_NORMAL.
// We shall call sched_setscheduler() and change to realtime policy
// like SCHED_RR or SCHED_FIFO.
let sched_param = nc::sched_param_t { sched_priority: 12 };
let ret = unsafe { nc::sched_setparam(0, &sched_param) };
assert_eq!(ret, Err(nc::EINVAL));
