Function amem_graph_get_content 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn amem_graph_get_content(
    graph: *mut c_void,
    node_id: u64,
    buffer: *mut c_char,
    buffer_size: u32,
) -> i32

Get a node’s content. Writes to buffer. Returns content length or error.

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.
