992 | * EXPORTED afs_Analyze |
---|
993 | * |
---|
994 | * Description: |
---|
995 | * Analyze the outcome of an RPC operation, taking whatever support |
---|
996 | * actions are necessary. |
---|
997 | * |
---|
998 | * Arguments: |
---|
999 | * aconn : Ptr to the relevant connection on which the call was made. |
---|
1000 | * acode : The return code experienced by the RPC. |
---|
1001 | * afid : The FID of the file involved in the action. This argument |
---|
1002 | * may be null if none was involved. |
---|
1003 | * areq : The request record associated with this operation. |
---|
1004 | * op : which RPC we are analyzing. |
---|
1005 | * cellp : pointer to a cell struct. Must provide either fid or cell. |
---|
1006 | * |
---|
1007 | * Returns: |
---|
1008 | * Non-zero value if the related RPC operation should be retried, |
---|
1009 | * zero otherwise. |
---|
1010 | * |
---|
1011 | * Environment: |
---|
1012 | * This routine is typically called in a do-while loop, causing the |
---|
1013 | * embedded RPC operation to be called repeatedly if appropriate |
---|
1014 | * until whatever error condition (if any) is intolerable. |
---|
1015 | * |
---|
1016 | * Side Effects: |
---|
1017 | * As advertised. |
---|
1018 | * |
---|
1019 | * NOTE: |
---|
1020 | * The retry return value is used by afs_StoreAllSegments to determine |
---|
1021 | * if this is a temporary or permanent error. |
