Both the primary status code and the link status code are values of type unsigned int that are drawn from the same set of meaningful values. XFN reserves the values 0 through 127 for standard meanings. Currently, values and interpretations for the following codes are determined by XFN.

FN_SUCCESS

The operation succeeded.

FN_E_ATTR_NO_PERMISSION

The caller did not have permission to perform the attempted attribute operation.

FN_E_ATTR_VALUE_REQUIRED

The operation attempted to create an attribute without a value, and the specific naming system does not allow this.

FN_E_AUTHENTICATION_FAILURE

The identity of the client principal could not be verified.

FN_E_COMMUNICATION_FAILURE

An error occurred in communicating with one of the contexts involved in the operation.

FN_E_CONFIGURATION_ERROR

A problem was detected that indicated an error in the installation of the XFN implementation.

FN_E_CONTINUE

The operation should be continued using the remaining name and the resolved reference returned in the status.

FN_E_CTX_NO_PERMISSION

The client did not have permission to perform the operation.

FN_E_CTX_NOT_EMPTY

(Applies only to fn_ctx_destroy_subcontext().) The naming system required that the context be empty before its destruction, and it was not empty.

FN_E_CTX_UNAVAILABLE

Service could not be obtained from one of the contexts involved in the operation. This may be because the naming system is busy, or is not providing service. In some implementations this may not be distinguished from a communication failure.

FN_E_ILLEGAL_NAME

The name supplied to the operation was not a well- formed XFN composite name, or one of the component names was not well-formed according to the syntax of the naming system(s) involved in its resolution.

FN_E_E_INCOMPATIBLE_CODE_SETS

The operation involved character strings of incompatible code sets, or the supplied code set is not supported by the implementation.

FN_E_INSUFFICIENT_RESOURCES

Either the client or one of the involved contexts could not obtain sufficient resources (for example, memory, file descriptors, communication ports, stable media space, and so on) to complete the operation successfully.

FN_E_INVALID_ATTR_IDENTIFIER

The attribute identifier was not in a format acceptable to the naming system, or its content was not valid for the format specified for the identifier.

FN_E_INVALID_ATTR_VALUE

One of the values supplied was not in the appropriate form for the given attribute.

FN_E_INVALID_ENUM_HANDLE

The enumeration handle supplied was invalid, either because it was from another enumeration, or because an update operation occurred during the enumeration, or because of some other reason.

FN_E_INVALID_SYNTAX_ATTRS

The syntax attributes supplied are invalid or insufficient to fully specify the syntax.

FN_E_LINK_ERROR

There was an error in resolving an XFN link encountered during resolution of the supplied name.

FN_E_LINK_LOOP_LIMIT

A non-terminating loop (cycle) in the resolution can arise due to XFN links encountered during the resolution of a composite name. This code indicates either the definite detection of such a cycle, or that resolution exceeded an implementation-defined limit on the number of XFN links allowed for a single operation invoked by the caller.

FN_E_MALFORMED_LINK

A malformed link reference was encountered. For fn_ctx_lookup_link(), the name supplied resolved to a reference that was not a link.

FN_E_MALFORMED_REFERENCE

A context object could not be constructed from the supplied reference, because the reference was not properly formed.

FN_E_NAME_IN_USE

(Only for operations that bind names.) The supplied name was already in use.

FN_E_NAME_NOT_FOUND

Resolution of the supplied composite name proceeded to a context in which the next atomic component of the name was not bound.

FN_E_NO_SUCH_ATTRIBUTE

The object did not have an attribute with the given identifier.

FN_E_NO_SUPPORTED_ADDRESS

A context object could not be constructed from a particular reference. The reference contained no address type over which the context interface was supported.

FN_E_NOT_A_CONTEXT

Either one of the intermediate atomic names did not name a context, and resolution could not proceed beyond this point, or the operation required that the caller supply the name of a context, and the name did not resolve to a reference for a context.

FN_E_OPERATION_NOT_SUPPORTED

The operation attempted is not supported.

FN_E_PARTIAL_RESULT

The operation attempted is returning a partial result.

FN_E_SYNTAX_NOT_SUPPORTED

The syntax type specified is not supported.

FN_E_TOO_MANY_ATTR_VALUES

The operation attempted to associate more values with an attribute than the naming system supported.

FN_E_UNSPECIFIED_ERROR

An error occurred that could not be classified by any of the other error codes.
