cudaError_t cudaMemcpyToArrayAsync ( struct cudaArray *  dst, size_t  wOffset, size_t  hOffset, const void *  src, size_t  count, enum cudaMemcpyKind  kind, cudaStream_t  stream = 0   ) Copies count bytes from the memory area pointed to by src to the CUDA array dst starting at the upper left corner (wOffset, hOffset), where kind is one of cudaMemcpyHostToHost, cudaMemcpyHostToDevice, cudaMemcpyDeviceToHost, or cudaMemcpyDeviceToDevice, and specifies the direction of the copy. cudaMemcpyToArrayAsync() is asynchronous with respect to the host, so the call may return before the copy is complete. It only works on page-locked host memory and returns an error if a pointer to pageable memory is passed as input. The copy can optionally be associated to a stream by passing a non-zero stream argument. If kind is cudaMemcpyHostToDevice or cudaMemcpyDeviceToHost and stream is non-zero, the copy may overlap with operations in other streams. Parameters: dst  - Destination memory address wOffset  - Destination starting X offset hOffset  - Destination starting Y offset src  - Source memory address count  - Size in bytes to copy kind  - Type of transfer stream  - Stream identifier Returns: cudaSuccess, cudaErrorInvalidValue, cudaErrorInvalidDevicePointer, cudaErrorInvalidMemcpyDirection Note: Note that this function may also return error codes from previous, asynchronous launches.
