Hello, All!

I'm kinda new programmer to DJGPP and Allegro, I'm now writing a game (got
very interested in Allegro features, so I switched to DJGPP C from Borland
Pascal).

Allegro is a very good thing, but I've got some questions about C
programming:

I like Allegro DAT files, they are very well implemented when I need to get
pictures or sounds (just grfile[MY_PIC].dat), but it's real pain to access
strings of characters.

For example, I have a text file (CR/LF terminated strings) and I can parse
in really easy when I use real text file:

FILE *f = fopen(fname,"rt");

fscanf(f,"%[^\n]\n",maptitle);
fscanf(f,"%d",&mspace);
[...]
fclose(f);

But it gets really complicated when I try to "read" my text file that was
inserted in Allegro's DAT. For example, I can't just read integer number
from it - I need to read string that I'll convert later to integer.

I think that there should be an easier way just to use something for
emulating real text file for fscanf and likes functions. Anyone knows what
could it be?

Question number 2

I have an array of structures named Pl which index varies from 0 to 8
(Pl[0]...Pl[8]).
I need to save it all into single file. I've walked an easy way and written:

f = fopen("MYGAME.SAV","wb");
fwrite(Pl, sizeof(TPLAYER), 8, f);
fclose(f);

(TPLAYER is a type of Pl structure, f is a file that I've opened)

But this one doesn't work :( I've tried more complicated ones, like

for (i=0;i<=8;i++) {
  fwrite(Pl[i],sizeof(TPLAYER),1,f);
}

but these ones don't work either :( Anyone have any suggestions?

Please, also duplicate your answers with e-mail directly to me
(myakshin AT glasnet DOT ru). I'm not sure that I can
receive this newsgroup well...

Bye!
