\brief Returns the memory requirements of a CUDA mipmapped array

Returns the memory requirements of a CUDA mipmapped array in \p memoryRequirements If the CUDA mipmapped array is not allocated with flag ::CUDA_ARRAY3D_DEFERRED_MAPPING ::CUDA_ERROR_INVALID_VALUE will be returned.

The returned value in ::CUDA_ARRAY_MEMORY_REQUIREMENTS::size represents the total size of the CUDA mipmapped array. The returned value in ::CUDA_ARRAY_MEMORY_REQUIREMENTS::alignment represents the alignment necessary for mapping the CUDA mipmapped array.

\return ::CUDA_SUCCESS ::CUDA_ERROR_INVALID_VALUE

\param[out] memoryRequirements - Pointer to ::CUDA_ARRAY_MEMORY_REQUIREMENTS \param[in] mipmap - CUDA mipmapped array to get the memory requirements of \param[in] device - Device to get the memory requirements for \sa ::cuArrayGetMemoryRequirements, ::cuMemMapArrayAsync
