Hi All, I'm writing a small piece of code to call fsfreeze/unfreeze that can be invoked by a RADOS notify. I have the basic watch/notify functionality working but I need to be able to determine if the notify message is to freeze or unfreeze, or maybe something completely unrelated. I'm looking at the rados_watchcb2_t callback and can see that the data payload is returned as a void pointer. This is where it all starts to go a little pear shaped for my basic C skills. I think I have to cast the pointer to a (char *) but I still can't seem to get anything useful from it. I've been following some of the tests in the Ceph source and they seem to use some sort of typedef called a bufferlist, is this what I need to try and look into? Does anyone have any pointers (excuse the pun) as to how I would read the text part of the payload from it? void watch_notify2_cb(void *arg, uint64_t notify_id, uint64_t cookie, uint64_t notifier_gid, void *data, size_t data_len) Many Thanks, Nick _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
