NAME

FN_identifier_t - an XFN identifier

DESCRIPTION

Identifiers are used to identify reference types and address types in an XFN reference, and to identify attributes and their syntax in the attribute operations.

An XFN identifier consists of an unsigned int, which determines the format of identifier, and the actual identifier, which is expressed as a sequence of octets.

The representation of this structure is defined by XFN as follows:

typedef struct {
     unsigned int format;
     size_t length;
     void * contents;
} FN_identifier_t;

XFN defines a small number of standard forms for identifiers.

FN_ID_STRING

The identifier is an ASCII string (ISO 646 ).

FN_ID_DCE_UUID

The identifier is an OSF DCE UUID in string representation.

(See the X/Open DCE RPC.)

FN_ID_ISO_OID_STRING

The identifier is an ISO OID in ASN.1 dot-separated integer

list string format. (See the ISO ASN.1.)

FN_ID_ISO_OID_BER

The identifier is an ISO OID in ASN.1 Basic Encoding Rules

(BER) format. (See the ISO BER .)
