查找“〜/库/应用程序支持"；来自C ++? [英] Finding "~/Library/Application Support" from C++?

问题描述

我已经编写了一个GTKmm应用程序，并且试图创建一些OS X增强功能.我想将配置文件存储在Application Support/myApp文件夹中，但是，我不知道找到该文件夹​​的正确方法.

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.

我尝试浏览Core Foundation库(我正在使用它来获取myApp.app路径)，但找不到任何东西.

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.

推荐答案

在C/C ++中执行此操作的正确方法:

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'

自然，这些都是非常古老的API，Apple不再建议使用它们.尽管如此，如果您想完全避免在代码库中使用Objective-C，就可以完成工作.

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.
