** [tickets:#561] CKPT: add "CkptArrivalCallback" as part of the CKPT API**

**Status:** accepted
**Created:** Tue Sep 03, 2013 10:33 AM UTC by Hans Feldt
**Last Updated:** Thu Oct 03, 2013 09:42 AM UTC
**Owner:** A V Mahesh (AVM)

The OpenSAF implementation of CKPT adds a feature that closes a gap identified 
and reported by SCOPE alliance in 
http://scope-alliance.org/sites/default/files/documents/CG_MW_Profile_07_07_16_v2.0.pdf

The OpenSAF declaration of the extra function is not in the standard API 
(saCkpt.h) but in cpsv_papi.h.

The purpose of this enhancement is to add this function to the standard API 
with in "SAF style". This includes:

* adding a new callback type SaCkptCheckpointReplicaUpdateCallbackT
* adding a new callback in SaCkptCallbacksT_o2
* adding a new saCkptInitialize_o2 that takes SaCkptCallbacksT_o2 as a parameter
* calling the callback when the local (?) replica is updated
* clearly define the semantics of the function in the CKPT PR doc
* saCkptInitialize_o2 available with version B.02.11

please comment!

An alternative is to skip the _o2 and go for _2 and B.03.01
