2177
2178Crossfire maintains a very simple database for extension use. It can
2179currently store anything that can be serialised using Storable, which
2180excludes objects.
2181
2182The parameter C<$family> should best start with the name of the extension
2183using it, it should be unique.
2184
2185=over 4
2186
2187=item $hashref = cf::db_get $family
2188
2189Return a hashref for use by the extension C<$family>, which can be
2190modified. After modifications, you have to call C<cf::db_dirty> or
2191C<cf::db_sync>.
2192
2193=item $value = cf::db_get $family => $key
2194
2195Returns a single value from the database
2196
2197=item cf::db_put $family => $hashref
2198
2199Stores the given family hashref into the database. Updates are delayed, if
2200you want the data to be synced to disk immediately, use C<cf::db_sync>.
2201

2203
2204Stores the given C<$value> in the family hash. Updates are delayed, if you
2205want the data to be synced to disk immediately, use C<cf::db_sync>.
2206

2209Marks the database as dirty, to be updated at a later time.
