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. cudaArrayDefault: This flag's value is defined to be 0 and provides default array allocation cudaArraySurfaceLoadStore: Allocates an array that can be read from or written to using a surface reference cudaArrayTextureGather: This flag indicates that texture gather operations will be performed on the array. width and height must meet certain size requirements. See cudaMalloc3DArray() for more details. Parameters: 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 Returns: cudaSuccess, cudaErrorMemoryAllocation Note: Note that this function may also return error codes from previous, asynchronous launches.
