asSink

fun NSOutputStream.asSink(): RawSink(source)

Returns RawSink that writes to an output stream.

Use RawSink.buffered to create a buffered sink from it.

fun main() { 
   //sampleStart 
   val data = ByteArray(100) { it.toByte() }

val sink = outputStream.asSink().buffered()

sink.flush()

val writtenData = outputStream.propertyForKey(NSStreamDataWrittenToMemoryStreamKey) as NSData
assertContentEquals(data, writtenData.toByteArray())
