A Integer | undefined representing the process identifier (PID) of the child process. Until the child process has spawned successfully, the value is undefined. When the child process exits, then the value is undefined after the exit event is emitted.

spawnEvent

external val spawnEvent: EventInstance<Tuple>

stderr

external var stderr: ReadableStream?

A NodeJS.ReadableStream | null that represents the child process's stderr. If the child was spawned with options.stdio2 set to anything other than 'pipe', then this will be null. When the child process exits, then the value is null after the exit event is emitted.

stdout

external var stdout: ReadableStream?

A NodeJS.ReadableStream | null that represents the child process's stdout. If the child was spawned with options.stdio1 set to anything other than 'pipe', then this will be null. When the child process exits, then the value is null after the exit event is emitted.

Functions

addListener

external fun addListener(type: EventType, listener: EventListener)

eventNames

external fun eventNames(): ReadonlyArray<EventType>

getMaxListeners

external fun getMaxListeners(): Double

kill

external fun kill(): Boolean

Terminates the process gracefully. On POSIX, it uses SIGTERM but will ensure the process is reaped on exit. This function returns true if the kill is successful, and false otherwise.
