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