cudaError_t cudaMemcpy2DArrayToArray ( struct cudaArray *  dst, size_t  wOffsetDst, size_t  hOffsetDst, const struct cudaArray *  src, size_t  wOffsetSrc, size_t  hOffsetSrc, size_t  width, size_t  height, enum cudaMemcpyKind  kind = cudaMemcpyDeviceToDevice   ) Copies a matrix (height rows of width bytes each) from the CUDA array srcArray 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. wOffsetDst + width must not exceed the width of the CUDA array dst. wOffsetSrc + width must not exceed the width of the CUDA array src. 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 width  - Width of matrix transfer (columns in bytes) height  - Height of matrix transfer (rows) kind  - Type of transfer Returns: cudaSuccess, cudaErrorInvalidValue, cudaErrorInvalidMemcpyDirection Note: Note that this function may also return error codes from previous, asynchronous launches.
