Please note that this function is called for the first time from within the avahi_entry_group_new() context! Thus, in the callback you should not make use of global variables that are initialized only after your call to avahi_entry_group_new(). A common mistake is to store the AvahiEntryGroup pointer returned by avahi_entry_group_new() in a global variable and assume that this global variable already contains the valid pointer when the callback is called for the first time. A work-around for this is to always use the AvahiEntryGroup pointer passed to the callback function instead of the global pointer. */, void *userdata /**< This arbitrary user data pointer will be passed to the callback functon */); /** Clean up and free an AvahiEntryGroup object */ |
