| Parameter | Description |
|---|---|
| src | The buffer slice to read from. |
| dst | The array in the CPU memory that the contents of the buffer should be written to. The array must remain valid until the read operation is complete. Related content: IDeviceContext.Wait. |
| id | The ID of the event to use to track completion of the read. |
Read contents of a buffer from the context.
The memory that the BufferSlice<T0> points to can be transferred into a NativeArray<T0>. This is an asynchronous operation. Pass an EventID created with IDeviceContext.CreateEvent to track the completion status, if desired. This method returns immediately after enqueuing the command in the context.
Note: EventID is single-use. Once an EventID has been passed to this function, it may not be passed to subsequent IDeviceContext.WriteBuffer or IDeviceContext.ReadBuffer calls. Doing so will result in undefined behavior.
