Expand description

Asynchronous version of PidFd.

Implementations§

Source§

impl AsyncPidFd

Source

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.

Source

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

Wait for the process to complete.
