/**

* Get the directory where the application was run from.
|
|
*
|
|
* This is not necessarily a fast call, so you should call this once near
|
|
* startup and save the string if you need it.
|
|
*
|
|
* **Mac OS X and iOS Specific Functionality**: If the application is in a
|
|
* ".app" bundle, this function returns the Resource directory (e.g.
|
|
* MyApp.app/Contents/Resources/). This behaviour can be overridden by adding
|
|
* a property to the Info.plist file. Adding a string key with the name
|
|
* SDL_FILESYSTEM_BASE_DIR_TYPE with a supported value will change the
|
|
* behaviour.
|
|
*
|
|
* Supported values for the SDL_FILESYSTEM_BASE_DIR_TYPE property (Given an
|
|
* application in /Applications/SDLApp/MyApp.app):
|
|
*
|
|
* - `resource`: bundle resource directory (the default). For example:
|
|
* `/Applications/SDLApp/MyApp.app/Contents/Resources`
|
|
* - `bundle`: the Bundle directory. For example:
|
|
* `/Applications/SDLApp/MyApp.app/`
|
|
* - `parent`: the containing directory of the bundle. For example:
|
|
* `/Applications/SDLApp/`
|
|
*
|
|
* **Nintendo 3DS Specific Functionality**: This function returns "romfs"
|
|
* directory of the application as it is uncommon to store resources outside
|
|
* the executable. As such it is not a writable directory.
|
|
*
|
|
* The returned path is guaranteed to end with a path separator ('\' on
|
|
* Windows, '/' on most other platforms).
|
|
*
|
|
* The pointer returned is owned by the caller. Please call SDL_free() on the
|
|
* pointer when done with it.
|
|
*
|
|
* \returns an absolute path in UTF-8 encoding to the application data
|
|
* directory. NULL will be returned on error or when the platform
|
|
* doesn't implement this functionality, call SDL_GetError() for more
|
|
* information.

*

/**
|
|

|
*
|
|
* Get the "pref dir". This is meant to be where users can write personal
|
|
* files (preferences and save games, etc) that are specific to your
|
|
* application. This directory is unique per user, per application.
|
|
*
|
|
* This function will decide the appropriate location in the native
|
|
* filesystem, create the directory if necessary, and return a string of the
|
|
* absolute path to the directory in UTF-8 encoding.
|
|
*
|
|
* On Windows, the string might look like:
|
|
*
|
|
* `C:\\Users\\bob\\AppData\\Roaming\\My Company\\My Program Name\\`
|
|
*
|
|
* On Linux, the string might look like:
|
|
*
|
|
* `/home/bob/.local/share/My Program Name/`
|
|
*
|
|
* On Mac OS X, the string might look like:
|
|
*
|
|
* `/Users/bob/Library/Application Support/My Program Name/`
|
|
*
|
|
* You should assume the path returned by this function is the only safe place
|
|
* to write files (and that SDL_GetBasePath(), while it might be writable, or
|
|
* even the parent of the returned path, isn't where you should be writing
|
|
* things).
|
|
*
|
|
* Both the org and app strings may become part of a directory name, so please
|
|
* follow these rules:
|
|
*
|
|
* - Try to use the same org string (_including case-sensitivity_) for all
|
|
* your applications that use this function.
|
|
* - Always use a unique app string for each one, and make sure it never
|
|
* changes for an app once you've decided on it.
|
|
* - Unicode characters are legal, as long as it's UTF-8 encoded, but...
|
|
* - ...only use letters, numbers, and spaces. Avoid punctuation like "Game
|
|
* Name 2: Bad Guy's Revenge!" ... "Game Name 2" is sufficient.
|
|
*
|
|
* The returned path is guaranteed to end with a path separator ('\' on
|
|
* Windows, '/' on most other platforms).
|
|
*
|
|
* The pointer returned is owned by the caller. Please call SDL_free() on the
|
|
* pointer when done with it.
|
|
*
|
|
* \param org the name of your organization
|
|
* \param app the name of your application
