Get the directory where the application was run from.
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.
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:
bundle: the Bundle directory. For example:
parent: the containing directory of the bundle. For example:
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.
This function is available since SDL 2.0.1.
