fn_ctx_lookup_link (3)

    NAME
         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);
    
    DESCRIPTION
         This operation returns the XFN link bound to name.  The ter-
         minal 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.
    
    RETURN VALUES
         If   fn_ctx_lookup_link()  fails,  a  NULL  pointer  (0)  is
         returned.
    
    ERRORS
         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.

    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.
