I am trying to get the serial number of my device. I am quite c++ challenged and am struggling with this. Can someone point me to an example of how to call the deviceinfo.h functions.

More sepcifically I am trying to call deviceinfo_identifying_details_get_serial_number

Here is my failed attempt that does not compile.

Description    Resource    Path    Location    Type
cannot convert 'int*' to 'deviceinfo_identifying_details_t*' in initialization   

cannot convert 'deviceinfo_identifying_details_t' to 'deviceinfo_identifying_details_t*' for argument '1' to 'long long int deviceinfo_identifying_details_get_serial_number(deviceinfo_identifying_details_t*)'   

    deviceinfo_identifying_details_t * deviceInfo = new deviceInfo();
    deviceinfo_get_identifying_details(deviceInfo);
    long long deviceinfo_identifying_details_get_serial_number(deviceInfo);

You don't need to malloc or new the deviceinfo_identifying_details_t struct yourself.  Use the "get" and "free" functions provided:

long long serial_number = -1;
deviceinfo_identifying_details_t *id_details = NULL;

int rc = deviceinfo_get_identifying_details(&id_details);
if (BPS_SUCCESS == rc) {
    serial_number = deviceinfo_identifying_details_get_serial_number(id_details);
    deviceinfo_free_identifying_details(&id_details);
}

Note that your app must have the "read_device_identifying_information" capability. i.e. your bar descriptor must contain the line:

<permission>read_device_identifying_information</permission>
