Struct mio_pidfd::PidFd

pub struct PidFd { /* fields omitted */ }

A Linux pidfd abstraction that can be used to poll the exit status of multiple child processes using mio.

Implementations

impl PidFd

pub fn new(child: &Child) -> Result<Self>

Create a new pidfd from a child process. This may be registerd with a mio poll.

pub fn kill(&self, sig: c_int) -> Result<()>

Send a signal to the process using the pidfd. Use std::process::Child::kill() over this. This kill() is here only for the completeness of the pidfd system calls abstraction.

pub fn open(pid: pid_t, flags: c_uint) -> Result<Self>

Wrapper to pidfd_open system call. Use instead of new() when extra parameters are desired.

pub fn send_signal(
    &self,
    sig: c_int,
    info: Option<&siginfo_t>,
    flags: c_uint
) -> Result<()>

Wrapper to pidfd_send_signal system call. Use instead of kill() when extra parameters are desired.
