| XFN Interface Library Functions | fn_ctx_lookup_link(3XFN) |
| | fn_ctx_lookup_link - look up the link reference bound to a name |
SYNOPSIS
| |
cc [ flag ... ] file ... -lxfn [ library ... ]
#include <xfn/xfn.h>
FN_ref_t *fn_ctx_lookup_link(FN_ctx_t *ctx, const FN_composite_name_t *name, FN_status_t *status); |
| |
This operation returns the XFN link bound to name. The terminal atomic part of name must be bound to an XFN link.
The normal fn_ctx_lookup(3XFN) operation follows all links encountered, including
any bound to the terminal atomic part of name. This operation differs from the normal lookup in that when the terminal atomic part of name is an XFN link, this link is not followed, and the operation returns the link.
|
| |
If fn_ctx_lookup_link() fails, a NULL pointer (0) is returned.
|
| |
fn_ctx_lookup_link() sets status as described in FN_status_t(3XFN) and xfn_status_codes(3XFN). Of special relevance
for fn_ctx_lookup_link() is the following status code:
-
FN_E_MALFORMED_LINK
-
name resolved to a reference that was
not a link.

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.
