The various ORPCINFOFLAGS have the following meanings.
| Flag | Meaning |
| ORPCF_NULL | (Not a real flag. Merely a defined constant indicating the absence of any flag values.) |
| ORPCF_LOCAL | The destination of this call is on the same machine on which it originates. This value is never to be specified in calls which are not in fact local. |
| ORPCF_RESERVED1 | If ORPCF_LOCAL is set, then reserved for local use; otherwise, reserved for future use. |
| ORPCF_RESERVED2 | If ORPCF_LOCAL is set, then reserved for local use; otherwise, reserved for future use. |
| ORPCF_RESERVED3 | If ORPCF_LOCAL is set, then reserved for local use; otherwise, reserved for future use. |
| ORPCF_RESERVED4 | If ORPCF_LOCAL is set, then reserved for local use; otherwise, reserved for future use. |
Implementations may use the local and reserved flags to indicate any extra information needed for local calls. Note that if the ORPCF_LOCAL bit is not set and any of the other bits are set then the receiver should return a fault.
