Copies from device memory to device memory. dstDevice and srcDevice are the base pointers of the destination and source, respectively. ByteCount specifies the number of bytes to copy. Note that this function is asynchronous and can optionally be associated to a stream by passing a non-zero hStream argument
- Parameters:
-
| dstDevice | - Destination device pointer |
| srcDevice | - Source device pointer |
| ByteCount | - Size of memory copy in bytes |
| hStream | - Stream identifier |
- Returns:
- CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUE
- Note:
- Note that this function may also return error codes from previous, asynchronous launches.
