This function takes a variable of type icd_policy_api * plus a number of callbacks that can be saved for later use. Your plugin does whatever initialization it wishes to do (registering dbus handlers for example), saves any private data in the "private" field of the icd_policy_api structure (which may be a pointer to a data structure containing a bunch of data) and then fills in any appropriate function members of the icd_policy_api that this plugin wishes to listen for. |
