Getting a Nearest Equivalent Language

In this example, the system language is ELangCanadianEnglish and there is no exact match of the resource file on the system. The application calls BaflUtils::NearestLanguageFileV2() to get the closest match. There are three available resource files:

c:\FileMenu.rsc is the language-neutral resource file.
c:\FileMenu.r01 is for ELangEnglish.
c:\FileMenu.r10 is for ELangAmerican.

In the application, define a string with the neutral-language resource file name.
```
_LIT(KRscFilename, "C:\\FileMenu.rsc"); 
```

Create a session with the File Server to search the file system for available resource files.

RFs fileServerSession;
CleanupClosePushL(fileServerSession);
User::LeaveIfError(fileServerSession.Connect());

Construct a buffer to save a resource file name. The buffer takes the neutral-language resource file name as a input parameter to BaflUtils::NearestLanguageFileV2(). It will be updated with a new value after the call.
```
TBuf<256> filename;
filename.Copy(KRscFilename);
```
Define a TLanguage as a return parameter for the nearest equivalent language.
```
TLanguage lang=ELangNone;
```

Get the nearest language.

BaflUtils::NearestLanguageFileV2(fileServerSession, filename, lang);
...

Close the session with the File Server.

CleanupStack::PopAndDestroy (&fileServerSession);

The filename parameter is updated as "c:\\FileMenu.r10" which is the closest resource file for ELangCanadianEnglish. The lang parameter is returned as ELangAmerican (value 10) which is the nearest equivalent language.
