Os-specific extensions for Child

Required Methods§

source

fn pidfd(&self) -> Result<&PidFd, Error>

🔬This is a nightly-only experimental API. (linux_pidfd)

Obtains a reference to the PidFd created for this Child, if available.

A pidfd will only be available if its creation was requested with create_pidfd when the corresponding Command was created.

Even if requested, a pidfd may not be available due to an older version of Linux being in use, or if some other error occurred.

source

fn take_pidfd(&mut self) -> Result<PidFd, Error>

🔬This is a nightly-only experimental API. (linux_pidfd)

Takes ownership of the PidFd created for this Child, if available.

A pidfd will only be available if its creation was requested with create_pidfd when the corresponding Command was created.

Even if requested, a pidfd may not be available due to an older version of Linux being in use, or if some other error occurred.
