Re: Using librec

Cool, thanks!

So after doing the commands in your first email, I'd have to create an mset,  adapt the code in your second email, and then write to disk?

This is how you would create a rec_record_t with the following record:

  Foo: bar
  # this is a comment
  Bar: baz

The code:

  rec_field_t f1 = rec_field_new ("Foo", "bar");
  rec_comment_t c = rec_comment_new ("this is a comment");
  rec_field_t f2 = rec_field_new ("Bar", "baz");

  rec_record_t rec = rec_record_new ();
  rec_mset_t rec_elements = rec_record_mset (rec):

  rec_mset_append (rec_elements, MSET_FIELD, f1, MSET_ANY);
  rec_mset_append (rec_elements, MSET_COMMENT, c, MSET_ANY);
  rec_mset_append (rec_elements, MSET_FIELD, f2, MSET_ANY);

Working with record sets is similar: they also have a mset that contains
MSET_RECORD or MSET_COMMENT elements.
