#[non_exhaustive]pub enum WaitId<'a> {
All,
Pid(Pid),
Pgid(Option<Pid>),
PidFd(BorrowedFd<'a>),
}
Expand description
The identifier to wait on in a call to waitid
.
Variants (Non-exhaustive)§
This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
All
Wait on all processes.
Pid(Pid)
Wait for a specific process ID.
Pgid(Option<Pid>)
Wait for a specific process group ID, or the calling process’ group ID.
PidFd(BorrowedFd<'a>)
Wait for a specific process file descriptor.
