process-os-id

Arguments: process

Returns the operating system's identifier for the native thread associated with process, or nil if there is no current os-thread. A process that has never been enabled will have no thread and therefore return nil here. In a virtual threads model (non-:os-threads), an active process will return a non-nil value that will be otherwise meaningless.
