ReadBuffer<T>(BufferSlice<T>, NativeArray<T>)
Read contents of a buffer from the context.
public void ReadBuffer<T>(BufferSlice<T> src, NativeArray<T> dst) where T : struct
Parameters
The buffer slice to read from.
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.
Remarks
The memory that the buffer slice points to can be transferred into a NativeArray<T>. On the reference context this method is equivalent to ReferenceContext.GetNativeArray because they both finish the read immediately without the need for synchronization.
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.
ReadBuffer<T>(BufferSlice<T>, NativeArray<T>, EventID)
Read contents of a buffer from the context.
public void ReadBuffer<T>(BufferSlice<T> src, NativeArray<T> dst, EventID id) where T : struct
Parameters
The buffer slice to read from.
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.
The ID of the event to use to track completion of the read.
