* Here are some example results for Windows, Linux, and MacOS:

* -------------------------------------------------------
* Windows sample output

* {
*   "adapters": [
*     {
*       "name": "Ethernet",
*       "description": "Intel(R) Ethernet Connection (2) I219-LM",

*       "ipv4": "192.168.56.1"

*       "description": "Bluetooth Device (Personal Area Network)",

*     }
*   ]
* }

* Note: The "description" element is only present when run on Windows.
* Here's sample code to get the MAC address for the "Ethernet" adapter
lcMacAddress = loJson.FindRecordString("adapters","name","Ethernet",1,"mac")
IF (loJson.LastMethodSuccess = 0) THEN
    ? "Failed to find MAC address for the Ethernet adapter"
ELSE
    ? "MAC address: " + lcMacAddress
ENDIF

* -------------------------------------------------------
* Linux Sample Output:

* {
*   "adapters": [
*     {
*       "name": "lo",
*       "mac": "",
*       "ipv4": "127.0.0.1",
*       "ipv6": "::1"
*     },
*     {
*       "name": "eth0",

*       "ipv4": "172.16.16.28",
*       "ipv6": "fe80::529a:4cff:fe43:1556"
*     }
*   ]
* }

* -------------------------------------------------------
* Android:

* On Android, accessing the MAC address directly is restricted on modern Android versions (API level 23 and above) due to privacy and security concerns. 
* Apps targeting Android 6.0 (API level 23) or higher cannot access the MAC address of the device using standard APIs.
* If you're developing for modern Android, consider using alternative identifiers (e.g., instance IDs) instead of the MAC address, as recommended by Google.
* 
* Chilkat will not return MAC addresses for Android, regardless of the API level.
* Only IP addresses are returned for Android.

* MacOS Sample Output:
