Reconciliation

After gathering all attribute lists, the signaler application must reconcile them. Successful reconciliation results in a new, reconciled attribute list that satisfies all applications' requirements. If NvSciSync cannot create such a list because attributes contradict, it instead creates an attribute list that describes the conflicts in more detail. In the example below, assume that waiterAttrList1 and waiterAttrList2 were created in the same process, so the variables are visible.

NvSciSyncAttrList unreconciledList[3] = {NULL};
NvSciSyncAttrList reconciledList = NULL;
NvSciSyncAttrList newConflictList = NULL;
NvSciError err; 
unreconciledList[0] = signalerAttrList;
unreconciledList[1] = waiterAttrList1;
unreconciledList[2] = waiterAttrList2;
err = NvSciSyncAttrListReconcile(
        unreconciledList,        /* array of unreconciled lists */
        3,                       /* size of this array */
        &reconciledList,         /* output reconciled list */
        &newConflictList);       /* conflict description filled in case of reconciliation failure */
if (err != NvSciError_Success) {
    goto fail;
}
/* ... */
NvSciSyncAttrListFree(reconciledList);
NvSciSyncAttrListFree(newConflictList);

NvSciSync recognizes which attribute lists are reconciled and which are not. Some NvSciSync APIs that take NvSciSyncAttrList expect the list to be reconciled.
