IDeviceContext.CreateEvent

Returns

EventID Unique identifier for the newly created event.

Description

Creates a synchronization event for tracking asynchronous operations.

Events provide a mechanism to track the completion status of asynchronous operations such as ReadBuffer and WriteBuffer. Each event can be used only once. After being passed to a read or write operation, it cannot be reused.

Use Wait to block until an event completes, or IsCompleted to check completion status without blocking.

Important: Events are single-use and must be destroyed with DestroyEvent after use to prevent resource leaks.

// Create an event to track a write operation
var writeEvent = context.CreateEvent();
context.WriteBuffer(bufferSlice, inputData, writeEvent);

// Check if the operation completed
if (context.IsCompleted(writeEvent))
{
    Console.WriteLine("Write operation completed");
    context.DestroyEvent(writeEvent);
}
