cudaError_t cudaMemcpyArrayToArray ( struct cudaArray *  dst, size_t  wOffsetDst, size_t  hOffsetDst, const struct cudaArray *  src, size_t  wOffsetSrc, size_t  hOffsetSrc, size_t  count, enum cudaMemcpyKind  kind = cudaMemcpyDeviceToDevice   ) Copies count bytes from the CUDA array src starting at the upper left corner (wOffsetSrc, hOffsetSrc) to the CUDA array dst starting at the upper left corner (wOffsetDst, hOffsetDst) where kind is one of cudaMemcpyHostToHost, cudaMemcpyHostToDevice, cudaMemcpyDeviceToHost, or cudaMemcpyDeviceToDevice, and specifies the direction of the copy. Parameters: dst  - Destination memory address wOffsetDst  - Destination starting X offset hOffsetDst  - Destination starting Y offset src  - Source memory address wOffsetSrc  - Source starting X offset hOffsetSrc  - Source starting Y offset count  - Size in bytes to copy kind  - Type of transfer Returns: cudaSuccess, cudaErrorInvalidValue, cudaErrorInvalidMemcpyDirection Note: Note that this function may also return error codes from previous, asynchronous launches.
