+SC Status Change Callback
+=========================
+Enhancement supports two resources for application to know about
+SC joining and leaving the cluster.
+
+Information about the resources:
+* A callback that will be invoked by AMFA whenever a SC joins cluster and
+ both SCs leaves cluster if SC Absence feature is enabled.
+
+ Callback and its argument:
+
+ void (*OsafAmfSCStatusChangeCallbackT)(OsafAmfSCStatusT state)
+ where OsafAmfSCStatusT is defined as:
+ typedef enum {
+ OSAF_AMF_SC_PRESENT = 1,
+ OSAF_AMF_SC_ABSENT = 2,
+ } OsafAmfSCStatusT;
+
+ This callback can be integrated
+ with standard AMF component (even with legacy one also).
+* An API to register/install above callback function:
+ void osafAmfInstallSCStatusChangeCallback(
+ void (*OsafAmfSCStatusChangeCallbackT)(OsafAmfSCStatusT status));
+
+Note: OsafAmfSCStatusT and API is declared in saAmf.h
+
+Also an application amf_sc_status_app.c to demonstrate the usage
+is added in samples/amf/sa_aware/.
