Finding "~/Library/Application Support" from C++?

Question

I've written a GTKmm application and I'm trying to create some OS X enhancements. I'd like to store my configuration file in the Application Support/myApp folder, however, I can't figure out the proper way to locate this folder.

I've tried looking through the Core Foundation library (that I'm using to get my myApp.app path) but I can't find anything.

Proper way to do it in C/C++:

#include <CoreServices/CoreServices.h>

FSRef ref;
OSType folderType = kApplicationSupportFolderType;
char path[PATH_MAX];

FSFindFolder( kUserDomain, folderType, kCreateFolder, &ref );

FSRefMakePath( &ref, (UInt8*)&path, PATH_MAX );

// You now have ~/Library/Application Support stored in 'path'

Naturally, those are very old APIs and their use is no longer recommended by Apple. Despite that it gets the job done if you want to avoid Objective-C completely in your codebase.
