Questionbluetooth hci function fails to execute hci_read_class_of_dev Pin

I need a small help finding my bluetooth hci problem.
The attached snippet fails to execute when all passed parameters are correct.

Execution stops at function like wrong parameters are being passed.
But it compiles / links.

For troubleshooting purposes I added 1 to device descriptor parameter and the function run and returns an error as expected.

I am not sure what is the purpose of "to" - time-out parameter?

Here is function prototype

int hci_read_class_of_dev(int dd, uint8_t *cls, int to);


What is odd - to write class I need uint32_t, but read wants only uint8_t.



C++
<pre>#ifdef DEBUG

// verify default hci0 
			system("hciconfig hci0 class");
			cout << "device descriptor " << dev_descriptor << endl;
#endif
			uint8_t *device_class = {0};
			int timeout = 0;
			if (hci_read_class_of_dev(dev_descriptor+1, device_class, timeout)) {
				perror("FAILURE");

			} else {
#ifdef DEBUG
				perror("SUCCESS");
				cout << "@line " << __LINE__ << endl;
#endif
			}



Thanks
Cheers
