Struct Comm

pub struct Comm {
    pub record_id: Option<RecordId>,
    pub by_execve: bool,
    pub task: Task,
    pub comm: CString,
}

Process name (comm) has been changed.

Examples

use perf_event_open::config::{Cpu, Opts, Proc};
use perf_event_open::count::Counter;
use perf_event_open::event::sw::Software;

let event = Software::Dummy;
let target = (Proc::CURRENT, Cpu::ALL);

let mut opts = Opts::default();
opts.extra_record.comm = true;

let counter = Counter::new(event, target, opts).unwrap();
let sampler = counter.sampler(5).unwrap();

counter.enable().unwrap();

// Change the process name to "foo" to trigger the `Comm` record.
unsafe { libc::prctl(libc::PR_SET_NAME, c"foo".as_ptr()) };

let mut iter = sampler.iter();
while let Some(it) = iter.next() {
    println!("{:-?}", it);
}

Fields
