Function acb_graph_get_unit_file 

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

Get a unit’s file path. Writes to buffer. Returns path length or error code.

Safety

graph must be a valid handle. buffer must point to at least buffer_size bytes of writable memory.
