Type Alias riot_sys::ble_gatt_attr_fn

pub type ble_gatt_attr_fn = Option<unsafe extern "C" fn(conn_handle: u16, error: *const ble_gatt_error, attr: *mut ble_gatt_attr, arg: *mut c_void) -> c_int>;

The host will free the attribute mbuf automatically after the callback is executed. The application can take ownership of the mbuf and prevent it from being freed by assigning NULL to attr->om.
