The ID argument for waitid

Variants§

§

All

Wait for any child

§

Pid(Pid)

Wait for the child whose process ID matches the given PID

§

PGid(Pid)

Wait for the child whose process group ID matches the given PID

If the PID is zero, the caller’s process group is used since Linux 5.4.

§

PIDFd(BorrowedFd<'fd>)

Wait for the child referred to by the given PID file descriptor
