Enum `Id`

pub enum Id<'fd>

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
