Interface CUstreamCallbackI

  • All Superinterfaces:
    CallbackI, CallbackI.V, Pointer
    All Known Implementing Classes:
    CUstreamCallback
    Functional Interface:
    This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

    @FunctionalInterface
    public interface CUstreamCallbackI
    extends CallbackI.V
    Instances of this interface may be passed to the StreamAddCallback method.

     void (*) (
         CUstream hStream,
         CUresult status,
         void *userData
     )
