int elektraNotificationContract | ( | KeySet * | contract | ) |
Creates a contract for use with kdbOpen() that sets up notifications.
When you call kdbOpen() with this contract, the internalnotification
plugin will be mounted automatically. This allows you to call other elektraNotification*
functions.
If you need to configure notification transport plugins, you should manually add the relevant keys to contract
.
contract | The keyset into which the contract is written. |
-1 | if contract is NULL |
0 | on success |
