Examples

Query electricity

```c

include "yxy.h"

void query() { char uid[] = "123456789\0"; char *session = auth(uid); if (session == NULL) { printf("auth error\n"); return; } else { printf("session: %s\n", session); }

ele_result *e;
int code = query_ele(session, &e);
if (code) {
  printf("query error: %d\n", code);
  return;
}

free_c_string(session);

printf("room: %s\nstatus: %s\ntotal surplus: %f %f\nsurplus: %f "
       "%f\nsubsidy: %f %f\n",
       e->display_room_name, e->room_status, e->total_surplus,
       e->total_amount, e->surplus, e->surplus_amount, e->subsidy,
       e->subsidy_amount);

free_ele_result(e);

} ```

App login (query uid)

```c

include "yxy.h"

       l_result->bind_card_status);

free_login_result(l_result); // remember to free the memory
free_c_string(handle.device_id);

} ```
