NAME
     fn_attr_create_subcontext - create a subcontext in a context
     and associate attributes with newly created context

SYNOPSIS
     #include <xfn/xfn.h>

     FN_ref_t  *fn_attr_create_subcontext(FN_ctx_t  *ctx,   const
     FN_composite_name_t   *name,   const   FN_attrset_t  *attrs,
     FN_status_t *status);

DESCRIPTION
     This operation creates a new XFN context of the same type as
     the  target  context, that is, that context named by all but
     the terminal atomic component of  name, and binds it to  the
     supplied  composite  name.  In addition, attributes given in
     attrs are associated with the newly created context.

     The target context must already exist. The  new  context  is
     created  and  bound in the target context using the terminal
     atomic name in name. The operation returns  a  reference  to
     the newly created context.

RETURN VALUES
     fn_attr_create_subcontext() returns a reference to the newly
     created  context;  if the operation fails, it returns a NULL
     pointer.

ERRORS
     fn_attr_create_subcontext()  sets  status  as  described  in
     FN_status_t(3XFN)  and  xfn_status_codes(3XFN).  Of  special
     relevance for this operation is the following status code:

     FN_E_NAME_IN_USE
           The terminal atomic name already exists in the  target
           context.

ATTRIBUTES
     See attributes(5) for descriptions of the  following  attri-
     butes:

    |       ATTRIBUTE TYPE        |       ATTRIBUTE VALUE       |
