That's a partial path, relative to the current working directory.
Have you set the current working directory? You'd do that using the
chdir() function.
When I launch my application, this instructions are executed, but
I'm unable to locate where my file is written.
Well, the current working directory is set differently depending on
how your app is launched. I think Finder and Xcode behave differently,
one uses / and another uses the directory containing your app. You'll
have to query the current working directory to find our where your app
ends up, or just use an absolute path to make sure it ends up in a
place where you want it.
Wich path I've to use in (1.) to see my file written in the same
location where my app is?
If your application is a regular MacOS bundle, you could use
NSBundle, which lets you get the path of your application bundle as an
NSString. You can then get a char* containing this as a path that C++
understands using NSString's fileSystemRepresentation method.
But really, you shouldn't assume you can write to the directory
where your app is. So, generally you should either ask the user where
to put your files, or use a standard location, like Application
Support, Documents, or in your case probably ~/Library/Logs/.
If you have other support files that are read-only, you'd best put
them in your app bundle's "Resources" folder and use NSBundle's
pathForResource:ofType: method to get an NSString with the absolute
path to it, and then use that to actually access the path.
