You wouldn't need a file name if you wrote the data as an in-line command=
:
  plot '-'
  xx xx xx
  xx xx xx
  E
and then passed the FILE pointer directly to load_file().

So the code would look like:
=09pre1 =3D tmpfile();  data =3D tmpfile(); post1 =3D tmpfile();
=09fprintf(pre1, buf1);=09/* write preliminary commands */
=09fprintf(data, buf2);=09/* write inline data for plot */
=09fprintf(post1, buf3);=09/* write any trailing commands */
=09rewind(pre1); rewind(data); rewind(post1);
=09load_file(pre1, ...);
=09load_file(data, ...);
=09load_file(post1, ...);


> =09save set 'tmp_file2'

A similar trick should work here:
=09save_set(savefp=3Dtmpfile());
=09...
=09load_file(savefp, ...);
