How do I get a local host name using the API
Which host name? TCP/IP host name? Windows network name?
TCP/IP host name is very easy. Just use a String to IP node with the input empty and then feed it into IP to String and you receive the current TCP/IP host name for your machine. One complication is that the default IP address may not be what is your internet facing address so it may not have a DNS name. If you enable Multiple IP in the right click menu for the String to IP node you get back an array of IP addresses, one for each network adapter (that includes virtual network adapters) in your system and you can query their name until you get one that is not a dot format address.
Windows host name is more complicated as there are various variants. The most common name (and least meaningful) can be retrieved with the GetComputerName() Windows API as described here. It's in kernel32.dll and there are many VIs around that already call this function.

You could try .NET instead. I find Dns.GetHostName works fine.
The Win32 API is still fully functional and accessible unless you run on a Windows IoT (non Enterprise) platform.
Both VIs work fine on my computer using Windows 10 and LabVIEW 2018.
The problem is likely that the library path got somehow messed up. There should be ONLY kernel32.dll and nothing else in the library path box. Also I have no idea why the name of the variable got localized. They were standard ASCII characters and should not be renamed no matter what locale your computer is using.
Ohhh you didn't download the VIs in the links I provided but created your own. A LabVIEW string handle is NOT compatible with a LPSTR pointer. Download the VI in the second link and use that instead of trying to do your own experiments when not understanding the C datatypes.
