Struct PidFd

pub struct PidFd(/* private fields */);

A process file descriptor.

Implementations

impl PidFd

pub fn from_pid(pid: pid_t) -> Result<Self>

Create a process file descriptor from a PID.

You can get a process ID from std::process::Child by calling Child::id.

As long as this process has not yet waited on the child process, and has not blocked SIGCHLD, the process ID will not get reused, so it does not matter if the child process has already exited.

pub fn wait(&self) -> Result<ExitInfo>

Wait for the process to complete.

Trait Implementations

fn as_raw_fd(&self) -> RawFd

impl Drop for PidFd

fn drop(&mut self)
