cudaError_t cudaMemcpy2DToArray ( struct cudaArray *  dst, size_t  wOffset, size_t  hOffset, const void *  src, size_t  spitch, size_t  width, size_t  height, enum cudaMemcpyKind  kind   ) Copies a matrix (height rows of width bytes each) 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. spitch is the width in memory in bytes of the 2D array pointed to by src, including any padding added to the end of each row. wOffset + width must not exceed the width of the CUDA array dst. width must not exceed spitch. cudaMemcpy2DToArray() returns an error if spitch exceeds the maximum allowed. Parameters: dst  - Destination memory address wOffset  - Destination starting X offset hOffset  - Destination starting Y offset src  - Source memory address spitch  - Pitch of source memory width  - Width of matrix transfer (columns in bytes) height  - Height of matrix transfer (rows) kind  - Type of transfer Returns: cudaSuccess, cudaErrorInvalidValue, cudaErrorInvalidDevicePointer, cudaErrorInvalidPitchValue, cudaErrorInvalidMemcpyDirection Note: Note that this function may also return error codes from previous, asynchronous launches.
