CUresult cuArrayGetDescriptor ( CUDA_ARRAY_DESCRIPTOR pArrayDescriptor,
CUarray  hArray 
)

Returns in *pArrayDescriptor a descriptor containing information on the format and dimensions of the CUDA array hArray. It is useful for subroutines that have been passed a CUDA array, but need to know the CUDA array parameters for validation or other purposes.

Parameters:
pArrayDescriptor - Returned array descriptor
hArray - Array to get descriptor of
Returns:
CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUE, CUDA_ERROR_INVALID_HANDLE
Note:
Note that this function may also return error codes from previous, asynchronous launches.
