How can an app detect it's running under WINE?

[Alberto Massari]

Hi everybody,
I am working on making our software (Stylus Studio, 
http://www.stylusstudio.com) run under WINE, if this is feasible. To 
achieve this, I have already implemented a bunch of APIs (the application 
is built against the UNICODE version of the Win32 APIs) and fixed some bugs 
I hit (I already mailed the first patch to [e-mail]).

However, I would feel better if I could detect I am running under WINE and 
gracefully disable some functionalities that are not yet fully supported; 
is there any way to achieve this? Is there a WIN32 API (like, say, 
GetVersionEx) that can return a string like "Windows 2000 (WINE)" or is 
WINE trying to be as stealth as possible?

Thanks in advance,

Alberto

You can query for example the wine registry entries.

http://www.winehq.org/FAQ/ would have been answering this in countless
cases already.

I look at this the same way I do those browser-sniffing scripts many 
websites use.  As an Opera user I get really annoyed when I run into a site 
that kicks me out for no reason other than its user agent string.  "If not 
IE and not NS, go away."  Maybe this made sense when Opera was at version 
2, but not now at version 6-going-on-7.  Almost every time the site works 
fine if I just bypass the silly check.

My suggestion is whenever possible check for features, not version strings.  
Just call the API and if it fails, then gracefully disable whatever 
functionality.  When some future version of Wine supports that API, it will 
just start working without any further effort on your part.  An added 
benefit is that whichever Wine developer is implementing that feature will 
have your app to test with.  Also have some sympathy for the poor Wine 
developer tearing his hair out trying to figure out why your app behaves 
differently in Wine vs. Windows no matter how perfect his shiny new 
DX12/DCOM/HAL/TANSTAAFL implementation is. :)
