Why not use something like this:

        char *buffer;
        size_t buffer_size;
        AG_Textbox *tb;
        ...
        tb = AG_TextboxNew(parent, AG_TEXTBOX_MULTILINE, NULL);
        AG_TextboxBindUTF8(tb, buffer, buffer_size);

Then you can simply append to the buffer:

        strlcat(buffer, "foo", buffer_size);
