| id | ID of the event. |
bool Returns true of the event completed successfully.
Wait for an asynchronous event.
This is a blocking method which stalls the current CPU thread until the operation represented by the EventID is complete. Adding a stall can have a significant performance impact during regular execution. To avoid stalls, call IDeviceContext.Wait at the end of your sequence of operations.
IDeviceContext ctx = new RadeonRaysContext();
ctx.Initialize();
uint length = 8;
var input = new NativeArray<byte>((int)length, Allocator.Persistent);
for (int i = 0; i < length; ++i)
input[i] = (byte)i;
var output = new NativeArray<byte>((int)length, Allocator.Persistent);
BufferID id = ctx.CreateBuffer(8);
var writeEvent = ctx.CreateEvent();
ctx.WriteBuffer(id.Slice<byte>(), input, writeEvent);
var readEvent = ctx.CreateEvent();
ctx.ReadBuffer(id.Slice<byte>(), output, readEvent);
bool flushOk = ctx.Flush();
Assert.IsTrue(flushOk);
bool eventOk = ctx.Wait(writeEvent);
Assert.IsTrue(eventOk);
// The event has completed.
input.Dispose();
Assert.IsTrue(ctx.IsCompleted(readEvent));
ctx.DestroyEvent(readEvent);
ctx.DestroyEvent(writeEvent);
ctx.DestroyBuffer(id);
for (int i = 0; i < length; ++i)
Assert.AreEqual((byte)i, output[i]);
output.Dispose();
ctx.Dispose();
