|

838 | |
|

839 | Crossfire maintains a very simple database for extension use. It can |
|
|
840 | currently store anything that can be serialised using Storable, which |
|
|
841 | excludes objects. |
|
|
842 | |
|
|
843 | The parameter C<$family> should best start with the name of the extension |
|
|
844 | using it, it should be unique. |

847 | |
|
|
848 | =item $hashref = cf::db_get $family |
|
|
849 | |
|
|
850 | Return a hashref for use by the extension C<$family>, which can be |
|
|
851 | modified. After modifications, you have to call C<cf::db_dirty> or |
|
|
852 | C<cf::db_sync>. |

853 | |
|
