#[unsafe(no_mangle)]
pub unsafe extern "C" fn hdds_reader_take(

Take data from a topic (non-blocking)

Safety

• reader must be a valid pointer returned from hdds_reader_create
• data_out must point to a valid buffer of at least max_len bytes
• len_out must be a valid pointer to write the actual data length
