Function amem_graph_node_count 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn amem_graph_node_count(
    graph: *mut c_void,
) -> u64

Get node count.

Safety

The caller must ensure that all pointer arguments are valid and non-null (unless the function explicitly handles null pointers), and that any pointed-to data is valid for the expected type and lifetime.
