Function ioprio::set_priority

pub fn set_priority(target: Target, priority: Priority) -> Result<()>

Set the I/O priority of the processes of the given target.

Note that increasing the priority class to real-time, will require elevated privileges (namely CAP_SYS_ADMIN). Additionally, this process must also have the permissions to modify the target process or group, or have CAP_SYS_NICE.

Refer to ioprio_set(2) for further information.
