cudaError_t cudaMallocArray ( struct cudaArray **  array,
const struct cudaChannelFormatDesc desc,
size_t  width,
size_t  height = 0,
unsigned int  flags = 0 

Allocates a CUDA array according to the cudaChannelFormatDesc structure desc and returns a handle to the new CUDA array in *array.

The cudaChannelFormatDesc is defined as:

    struct cudaChannelFormatDesc {
        int x, y, z, w;
    enum cudaChannelFormatKind f;
where cudaChannelFormatKind is one of cudaChannelFormatKindSigned, cudaChannelFormatKindUnsigned, or cudaChannelFormatKindFloat.

The flags parameter enables different options to be specified that affect the allocation, as follows.

array - Pointer to allocated array in device memory
desc - Requested channel format
width - Requested array allocation width
height - Requested array allocation height
flags - Requested properties of allocated array
cudaSuccess, cudaErrorMemoryAllocation
Note that this function may also return error codes from previous, asynchronous launches.
