## Description

The routines in this module provide a simple way to keep track of users' scores in a game.

In order to acommodate file ownership permissions, the game application should be installed setgid games and the scoretable should only be writable by the games group. The program should call `gnome_score_init()` as soon as possible inside the `main()` routine. This will open a pair of pipes to a child process which can read and write the score table and then will drop the group privileges of the main program back to the user's normal group id.

## Details

### gnome_score_init ()

    gint                gnome_score_init                    (const gchar *gamename);

### Warning

`gnome_score_init` is deprecated and should not be used in newly-written code.

GNOME games should call this routine as the first statement in `main()` if they have been installed setgid to the "games" group. It performs the intialization required to later record information in the scores table and then drops the groups privileges.

`gamename` : | Identifies the game name.
Returns : | `0` on success, returns `-1` on failure.

### gnome_score_log ()

    gint                gnome_score_log                     (gfloat score,
                                                             const gchar *level,
                                                             gboolean higher_to_lower_score_order);

### Warning

`gnome_score_log` is deprecated and should not be used in newly-written code.

Logs a score entry for the user. You should call this every time a game ends. This function takes care of working out whether the user's score made it into the ten best scores and, if so, records it in the table.

`score` : | The score achieved by the user in this game
`level` : | The level on which the score was obtained
`higher_to_lower_score_order` : | Set to `TRUE` if high scores are better than low scores.
Returns : | `0` on failure and the number of bytes written otherwise.

### gnome_score_get_notable ()

    gint                gnome_score_get_notable             (const gchar *gamename,
                                                             const gchar *level,
                                                             gchar ***names,
                                                             gfloat **scores,
                                                             time_t **scoretimes);

### Warning

`gnome_score_get_notable` is deprecated and should not be used in newly-written code.

Fetches the most notable players on `gamename` at level `level`.

`gamename` : | The name of the game we want to fetch information from.
`level` : | The level for which we want to pull information.
`names` : | An array of strings is returned at the address pointed here
`scores` : | An array of gfloats is returned at the address pointed here
`scoretimes` : | An array of time_t is returned at the address pointed here
Returns : | The number of scores returned. The `names`, `scores` and `scoretime` pointers point to regions that were allocated with `g_malloc()` with the contents.
