258 | cf::wait_for_tick_begin only returns directly I<after> the tick |
125 | processing has been done. Call C<< ->wait >> on them to maximise the |
259 | processing (and consequently, can only wake one thread per tick), while |
126 | window of cpu time available, or simply to synchronise to the server tick. |
260 | cf::wait_for_tick wakes up all waiters after tick processing. |
|
|
261 | |
|
|
262 | Note that cf::wait_for_tick will immediately return when the server is not |
|
|
263 | ticking, making it suitable for small pauses in threads that need to run |
|
|
264 | when the server is paused. If that is not applicable (i.e. you I<really> |

2114 | =head2 EXTENSION DATABASE SUPPORT |
|
|
2115 | |
|
|
2116 | Crossfire maintains a very simple database for extension use. It can |
|
|
2117 | currently store anything that can be serialised using Storable, which |
|
|
2118 | excludes objects. |
|
|
2119 | |
|
|
2120 | The parameter C<$family> should best start with the name of the extension |
|
|
2121 | using it, it should be unique. |
|
|
2122 | |
|
|
2123 | =over 4 |
|
|
2124 | |
|
|
2125 | =item $hashref = cf::db_get $family |
|
|
2126 | |
|
|
2127 | Return a hashref for use by the extension C<$family>, which can be |
|
|
2128 | modified. After modifications, you have to call C<cf::db_dirty> or |
|
|
2129 | C<cf::db_sync>. |
|
|
2130 | |
|
|
2131 | =item $value = cf::db_get $family => $key |
|
|
2132 | |
|
|
2133 | Returns a single value from the database |
|
|
2134 | |
|
|
2135 | =item cf::db_put $family => $hashref |
|
|
2136 | |
|
|
2137 | Stores the given family hashref into the database. Updates are delayed, if |
|
|
2138 | you want the data to be synced to disk immediately, use C<cf::db_sync>. |
|
|
2139 | |
|
|
2140 | =item cf::db_put $family => $key => $value |
|
|
2141 | |
|
|
2142 | Stores the given C<$value> in the family hash. Updates are delayed, if you |
|
|
2143 | want the data to be synced to disk immediately, use C<cf::db_sync>. |
|
|
2144 | |
|
|
2145 | =item cf::db_dirty |
|
|
2146 | |
|
|
2147 | Marks the database as dirty, to be updated at a later time. |
|
|
2148 | |
|
|
2149 | =item cf::db_sync |
|
|
2150 | |
|
