cudaError_t cudaMalloc3DArray ( struct cudaArray **  arrayPtr, const struct cudaChannelFormatDesc *  desc, struct cudaExtent  extent   ) Allocates a CUDA array according to the cudaChannelFormatDesc structure desc and returns a handle to the new CUDA array in *arrayPtr. The cudaChannelFormatDesc is defined as: struct cudaChannelFormatDesc { int x, y, z, w; enum cudaChannelFormatKind f; }; where cudaChannelFormatKind is one of cudaChannelFormatKindSigned, cudaChannelFormatKindUnsigned, or cudaChannelFormatKindFloat. cudaMalloc3DArray() is able to allocate 1D, 2D, or 3D arrays. A 1D array is allocated if the height and depth extent are both zero. For 1D arrays valid extent ranges are {(1, 8192), 0, 0}. A 2D array is allocated if only the depth extent is zero. For 2D arrays valid extent ranges are {(1, 65536), (1, 32768), 0}. A 3D array is allocated if all three extents are non-zero. For 3D arrays valid extent ranges are {(1, 2048), (1, 2048), (1, 2048)}. Note: Due to the differing extent limits, it may be advantageous to use a degenerate array (with unused dimensions set to one) of higher dimensionality. For instance, a degenerate 2D array allows for significantly more linear storage than a 1D array. Parameters: arrayPtr  - Pointer to allocated array in device memory desc  - Requested channel format extent  - Requested allocation size Returns: cudaSuccess, cudaErrorMemoryAllocation Note: Note that this function may also return error codes from previous, asynchronous launches.
