Methods

identityToken(int pid) → Future<String?>

An identity token that changes when the OS reuses pid for a different process — the process start time (or equivalent). Null when the process is not alive or the token is unobtainable.

isAlive(int pid) → Future<bool>

Whether a process with OS id pid is currently alive.

kill(int pid, {Duration grace}) → Future<bool>

Stops pid after verifying its identity. Unix hosts try SIGTERM, wait up to grace, then SIGKILL if still alive; Windows uses the process termination available through Dart's Process.killPid. Returns false when the process could not be safely stopped.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.
