my test code :

1#include <allegro.h>
2int main(void)
3{
DATAFILE* dfile;
BITMAP* backbuffer;
const char *name;
allegro_init();
install_keyboard();
set_color_depth(32);
set_gfx_mode(GFX_AUTODETECT_WINDOWED, 800, 600, 0, 0);

backbuffer = create_bitmap(800, 600);
clear_to_color(backbuffer, makecol(0,0,0));

dfile = load_datafile("running.dat");
if (!dfile)
{
  allegro_message("Error loading datafile");
  exit(-1);
}
for (int i= 0; dfile<i>.type != DAT_END; i++)
{
  name = get_datafile_property(dfile+i, DAT_NAME);
  allegro_message("name: %s", name);
}

readkey();
unload_datafile(dfile);
return 0;
30}
31END_OF_MAIN()

after I ran the programe, why did all objects's name is empty_string?

the contents of unning.dat:
<root>
[0] BMP 000_BMP
[2] BMP 001_BMP
[3] BMP 002_BMP
...
etc
int the grabber.exe , i found that every object include NAME property.
how can I get the their names in my program?
thnks a lot.

I found that after i used another *dat file to test the program, the program ran normally.

The running.dat was modified by me and I imported something else into it,
maybe I had destroyed it which result in the program's abnormity.
