What does gethostname return if compiled to wasm (eg in Webbrowser)?

[Kukulkano]

Hi. Is there a clear answer to the question about the result of gethostname in a WASM executable compiled by emscripten and run in WebBrowser or WebView (eg Android/iOS app)?

I try to debug issues in a WebView app and it points to this direction. Currently I assume gethostname to return the same on the platform itself and on wasm compiled executable and used in a WebView. But it seems not the same?

Before re-compiling the whole C project to identify issues with debug messages, is there maybe a clear answer to that somewhere in the documentation?
