NAME
     fn_ctx_lookup - look up name in context

SYNOPSIS
     cc [ flag ... ] file ... -lxfn [ library ... ]
     #include <xfn/xfn.h>

     FN_ref_t      *fn_ctx_lookup(FN_ctx_t      *ctx,       const
     FN_composite_name_t *name, FN_status_t *status);

DESCRIPTION
     This operation returns the reference bound to name  relative
     to the context ctx.

RETURN VALUE
     If the  operation  succeeds,  the  fn_ctx_lookup()  function
     returns  a handle to the reference bound to name. Otherwise,
     0 is returned and status is set appropriately.

ERRORS
     fn_ctx_lookup() sets  status as described  FN_status_t(3XFN)
     and  xfn_status_codes(3XFN).

APPLICATION USAGE
     Some naming services may not always have reference  informa-
     tion  for  all names in their contexts; for such names, such
     naming services may return a special  reference  whose  type
     indicates that the name
      is not bound to any address. This  reference  may  be  name
     service  specific  or it may be the conventional NULL refer-
     ence defined in the X/Open registry. See fns_references(5).
