DESCRIPTION

The result status of operations in the context interface and the attribute interface is encapsulated in an FN_status_t object. This object contains information about how the operation completed: whether an error occurred in performing the operation, the nature of the error, and information that helps locate where the error occurred. In the case that the error occurred while resolving an XFN link, the status object contains additional information about that error.

The context status object consists of several items of information:

primary status code

An unsigned int code describing the disposition of the operation.

resolved name

In the case of a failure during the resolution phase of the operation, this is the leading portion of the name that was resolved successfully. Resolution may have been successful beyond this point, but the error might not be pinpointed further.

resolved reference

The reference to which resolution was successful (in other words, the reference to which the resolved name is bound).

remaining name

The remaining unresolved portion of the name.

diagnostic message

This contains any diagnostic message returned by the context implementation. This message provides the context implementation a way of notifying the end-user or administrator of any implementation-specific information related to the returned error status. The diagnostic message could then be used by the end-user or administrator to take appropriate out-of-band action to rectify the problem.

link status code

In the case that an error occurred while resolving an XFN link, the primary status code has the value FN_E_LINK_ERROR and the link status code describes the error that occurred while resolving the XFN link.

resolved link name

In the case of a link error, this contains the resolved portion of the name in the XFN link.

resolved link reference

In the case of a link error, this contains the reference to which the resolved link name is bound.

remaining link name

In the case of a link error, this contains the remaining unresolved portion of the name in the XFN link.

link diagnostic message

In the case of a link error, this contains any diagnostic message related to the resolution of the link.

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. The values and interpretations for the codes are determined by XFN. See xfn_status_codes(3XFN) .

fn_status_create() creates a status object with status FN_SUCCESS . fn_status_destroy() releases the storage associated with stat . fn_status_copy() returns a copy of the status object stat . fn_status_assign() makes a copy of the status object src and assigns it to dst , releasing any old contents of dst . A pointer to the same object as dst is returned.

fn_status_code() returns the status code. fn_status_remaining_name() returns the remaining part of name to be resolved. fn_status_resolved_name() returns the part of the composite name that has been resolved. fn_status_resolved_ref() returns the reference to which resolution was successful. fn_status_diagnostic_message returns any diagnostic message set by the context implementation.

fn_status_link_code() returns the link status code. fn_status_link_remaining_name() returns the remaining part of the link name that has not been resolved. fn_status_link_resolved_name() returns the part of the link name that has been resolved. fn_status_link_resolved_ref() returns the reference to which resolution of the link was successful. fn_status_link_diagnostic_message() returns any diagnostic message set by the context implementation during resolution of the link.

fn_status_is_success() returns 1 if the status indicates success, 0 otherwise.

fn_status_set_success() sets the status code to FN_SUCCESS and clears all other parts of stat . fn_status_set() sets the non-link contents of the status object stat . fn_status_set_code() sets the primary status code field of the status object stat . fn_status_set_remaining_name() sets the remaining name part of the status object stat to name . fn_status_set_resolved_name() sets the resolved name part of the status object stat to name . fn_status_set_resolved_ref () sets the resolved reference part of the status objectstat to ref . fn_status_set_diagnostic_message() sets the diagnostic message part of the status object to msg .

fn_status_set_link_code() sets the link status code field of the status object stat to indicate why resolution of the link failed. fn_status_set_link_remaining_name() sets the remaining link name part of the status object stat to name . fn_status_set_link_resolved_name() sets the resolved link name part of the status object stat to name . fn_status_set_link_resolved_ref() sets the resolved link reference part of the status object stat to ref . fn_status_set_link_diagnostic_message() sets the link diagnostic message part of the status object to msg .

fn_status_append_resolved_name() appends as additional components name to the resolved name part of the status object stat . fn_status_append_remaining_name() appends as additional components name to the remaining name part of the status object stat . fn_status_advance_by_name() removes prefix from the remaining name, and appends it to the resolved name. The resolved reference part is set to resolved_ref . This operation returns 1 on success, 0 if the prefix is not a prefix of the remaining name.

RETURN VALUES

The fn_status_set_*() operations return 1 if the operation succeeds, 0 if the operation fails.

NOTES

The implementation of XFN in this Solaris release is based on the X/Open preliminary specification. It is likely that there will be minor changes to these interfaces to reflect changes in the final version of this specification. The next minor release of Solaris will offer binary compatibility for applications developed using the current interfaces. As the interfaces evolve toward standardization, it is possible that future releases of Solaris will require minor source code changes to applications that have been developed against the preliminary specification.
