C++
len = 8;
max_rsp = 255;
flags = IREQ_CACHE_FLUSH;
ii = (inquiry_info*) malloc(max_rsp * sizeof(inquiry_info));
cout << "TASK run hci_inquiry same as hcitoo scan  - takes time  @line "
        << dec << __LINE__ << endl;
num_rsp = hci_inquiry(dev_id, len, max_rsp, NULL, &ii, flags);
perror("STATUS hci_inquiry");
errno = 0;                 // reset !

if (num_rsp < 0)
    perror("FAILED (?) hci_inquiry");

for (i = 0; i < num_rsp; i++) {
    ba2str(&(ii + i)->bdaddr, addr);
    memset(name, 0, sizeof(name));
    if (hci_read_remote_name(dev_descriptor, &(ii + i)->bdaddr,
            sizeof(name), name, 0) < 0)
        strcpy(name, "[unknown]");
    printf("remote address  %s  remote name  %s\n", addr, name);
}


the question is
WHY does highlighted code throws an error
