NAME
     fn_ctx_unbind - unbind a name from a context

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


     int fn_ctx_unbind(FN_ctx_t *ctx,  const  FN_composite_name_t
     *name, FN_status_t *status);

DESCRIPTION
     This operation removes the terminal atomic name in name from
     the  the target context - that named by all but the terminal
     atomic part of name.

     This operation is successful even  if  the  terminal  atomic
     name  was  not  bound in target context, but fails if any of
     the intermediate names are  not  bound.  fn_ctx_unbind()  is
     idempotent.

RETURN VALUE
     The operation returns 1 if successful, and 0 otherwise.

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

     Certain naming systems may disallow unbinding a name if  the
     name  is  bound  to  an  existing  context in order to avoid
     orphan contexts that cannot be reached  via  any  name.   In
     such        situations,        the         status       code
     FN_E_OPERATION_NOT_SUPPORTED is returned.

APPLICATION USAGE
     In naming systems that support  attributes,  and  store  the
     attributes  along  with  the  names,  the  unbind  operation
     removes the name and its associated attributes.

     Normal   resolution   always   follows   links.     In    an
     fn_ctx_unbind()  operation,  resolution of name continues to
     the  target  context;  the  terminal  atomic  name  is   not
     resolved.  If  the  terminal atomic name is bound to a link,
     the link is not followed and the link itself is unbound from
     the terminal atomic name.
