CUresult cuArray3DCreate	(	CUarray *	pHandle,
		const CUDA_ARRAY3D_DESCRIPTOR *	pAllocateArray
	)

Creates a CUDA array according to the CUDA_ARRAY3D_DESCRIPTOR structure pAllocateArray and returns a handle to the new CUDA array in *pHandle. The CUDA_ARRAY3D_DESCRIPTOR is defined as:

    typedef struct {
        unsigned int Width;
        unsigned int Height;
        unsigned int Depth;
        CUarray_format Format;
        unsigned int NumChannels;
        unsigned int Flags;
    } CUDA_ARRAY3D_DESCRIPTOR;

where:

Width, Height, and Depth are the width, height, and depth of the CUDA array (in elements); the CUDA array is one-dimensional if height and depth are 0, two-dimensional if depth is 0, and three-dimensional otherwise; If the CUDA_ARRAY3D_LAYERED flag is set, then the CUDA array is a collection of layers, where Depth indicates the number of layers. Each layer is a 1D array if Height is 0, and a 2D array otherwise.

Format specifies the format of the elements; CUarray_format is defined as:

    typedef enum CUarray_format_enum {
        CU_AD_FORMAT_UNSIGNED_INT8 = 0x01,
        CU_AD_FORMAT_UNSIGNED_INT16 = 0x02,
        CU_AD_FORMAT_UNSIGNED_INT32 = 0x03,
        CU_AD_FORMAT_SIGNED_INT8 = 0x08,
        CU_AD_FORMAT_SIGNED_INT16 = 0x09,
        CU_AD_FORMAT_SIGNED_INT32 = 0x0a,
        CU_AD_FORMAT_HALF = 0x10,
        CU_AD_FORMAT_FLOAT = 0x20
    } CUarray_format;

NumChannels specifies the number of packed components per CUDA array element; it may be 1, 2, or 4;
Flags may be set to
- CUDA_ARRAY3D_LAYERED to enable creation of layered CUDA arrays. If this flag is set, Depth specifies the number of layers, not the depth of a 3D array.
- CUDA_ARRAY3D_SURFACE_LDST to enable surface references to be bound to the CUDA array. If this flag is not set, cuSurfRefSetArray will fail when attempting to bind the CUDA array to a surface reference.

Here are examples of CUDA array descriptions:

Description for a CUDA array of 2048 floats:

    CUDA_ARRAY3D_DESCRIPTOR desc;
    desc.Format = CU_AD_FORMAT_FLOAT;
    desc.NumChannels = 1;
    desc.Width = 2048;
    desc.Height = 0;
    desc.Depth = 0;

Description for a 64 x 64 CUDA array of floats:

    CUDA_ARRAY3D_DESCRIPTOR desc;
    desc.Format = CU_AD_FORMAT_FLOAT;
    desc.NumChannels = 1;
    desc.Width = 64;
    desc.Height = 64;
    desc.Depth = 0;

Description for a width x height x depth CUDA array of 64-bit, 4x16-bit float16's:

    CUDA_ARRAY3D_DESCRIPTOR desc;
    desc.FormatFlags = CU_AD_FORMAT_HALF;
    desc.NumChannels = 4;
    desc.Width = width;
    desc.Height = height;
    desc.Depth = depth;

Parameters:

	pHandle	- Returned array
	pAllocateArray	- 3D array descriptor

Returns:: CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUE, CUDA_ERROR_OUT_OF_MEMORY, CUDA_ERROR_UNKNOWN

Note:: Note that this function may also return error codes from previous, asynchronous launches.
