[−][src]Struct async_pidfd::PidFd

pub struct PidFd(_);

A process file descriptor.

Implementations

impl PidFd[src]

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

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>[src]

Wait for the process to complete.
