getUserStateDir

Returns a base directory in which to store state files specific to particular user.

On UNIX platforms this is determined using the mechanisms described in the XDG Base Directory Specification. In this case the directory retrieved will be XDG_STATE_HOME.

On Windows it follows XDG Base Directory Specification if XDG_STATE_HOME is defined. If XDG_STATE_HOME is undefined, the folder to use for local (as opposed to roaming) application data is used instead. See the documentation for FOLDERID_LocalAppData. Note that in this case on Windows it will be the same as what g_get_user_data_dir() returns.

The return value is cached and modifying it at runtime is not supported, as it’s not thread-safe to modify environment variables at runtime.
