available

abstract suspend fun available(): Long

Gets a snapshot of the currently available permits, always non negative.

The semaphore may be out of data instantly; use tryAcquire or tryAcquireN for acquires that immediately return if failed.

suspend fun main(): Unit {
  //sampleStart
  val semaphore = Semaphore(5)
  val available = semaphore.available()
  //sampleEnd
  println("available: $available")
