             CHARACTER*(*) NAME, INTEGER SIZEP)
NCID
The ncid for the group containing the opaque type.
XTYPE
The typeid for this opaque type, as returned by NF_DEF_COMPOUND, or NF_INQ_VAR.
NAME
The name of the opaque type will be copied here. It will be NF_MAX_NAME bytes or less.
SIZEP

Example

This example is from nf_test/ftst_vars3.F. 

     C     Use nf_inq_opaque and make sure we get the same answers as we did
     C     with nf_inq_user_type.
           retval = nf_inq_opaque(ncid, typeids(2), type_name, base_size)
           if (retval .ne. nf_noerr) call handle_err(retval)
