Function cuMipmappedArrayGetSparseProperties

pub unsafe extern "C" fn cuMipmappedArrayGetSparseProperties(
    sparseProperties: *mut CUDA_ARRAY_SPARSE_PROPERTIES,
    mipmap: CUmipmappedArray,
) -> CUresult

\brief Returns the layout properties of a sparse CUDA mipmapped array

Returns the sparse array layout properties in \p sparseProperties If the CUDA mipmapped array is not allocated with flag ::CUDA_ARRAY3D_SPARSE ::CUDA_ERROR_INVALID_VALUE will be returned.

For non-layered CUDA mipmapped arrays, ::CUDA_ARRAY_SPARSE_PROPERTIES::miptailSize returns the size of the mip tail region. The mip tail region includes all mip levels whose width, height or depth is less than that of the tile. For layered CUDA mipmapped arrays, if ::CUDA_ARRAY_SPARSE_PROPERTIES::flags contains ::CU_ARRAY_SPARSE_PROPERTIES_SINGLE_MIPTAIL, then ::CUDA_ARRAY_SPARSE_PROPERTIES::miptailSize specifies the size of the mip tail of all layers combined. Otherwise, ::CUDA_ARRAY_SPARSE_PROPERTIES::miptailSize specifies mip tail size per layer. The returned value of ::CUDA_ARRAY_SPARSE_PROPERTIES::miptailFirstLevel is valid only if ::CUDA_ARRAY_SPARSE_PROPERTIES::miptailSize is non-zero.

\return ::CUDA_SUCCESS ::CUDA_ERROR_INVALID_VALUE
