Hi
I am trying to get an allegro game/tutorial working on linux and found out itoa is not a good way to convert integer to ascii but I am having trouble implementing the substitution I found by searching the internet.

sprintf(buf, "%d", intval);

The lines in the code giving me the problem are

textout(buffer,pong_datafile[pong_text].dat,"Player 1 Score:",150,0,254);
textout(buffer,pong_datafile[pong_text].dat,itoa(score_p1,NULL,10),text_length(pong_dataf ile[pong_text].dat,"Player 1 Score:")+150,0,10);
textout(buffer,pong_datafile[pong_text].dat,"Player 2 Score:",350,0,254);
textout(buffer,pong_datafile[pong_text].dat,itoa(score_p2,NULL,10),text_length(pong_dataf ile[pong_text].dat,"Player 2 Score:")+350,0,10);

itoa is used (I suppose) to convert a number extracted from the pong.dat file to text. I can delete the two lines containing the itoa and it compiles fine of course.

How should sprintf be implemented in this context?

Thanks

Well, guessing that the 3rd parameter of textout() is a char*, you'd need to use sprintf() on a line of its own, and then put the buffer into textout().

Something like:

But I don't have textout() or itoa(), so I can't test it for you.

Thanks!

sprintf (buf, "%d", score_p1);
textout(buffer,pong_datafile[pong_text].dat,"Player 1 Score:",150,0,254);
textout(buffer,pong_datafile[pong_text].dat,buf,text_length(pong_datafile[pong_text].dat,"Player 1 Score:")+150,0,10);
textout(buffer,pong_datafile[pong_text].dat,"Player 2 Score:",350,0,254);
sprintf (buf, "%d", score_p2);
textout(buffer,pong_datafile[pong_text].dat,buf,text_length(pong_datafile[pong_text].dat,"Player 2 Score:")+350,0,10);

and I am in business. For char buf[bufsize] I just a put large enough a number to work:-)
Thanks again. I learned something!

BUFSIZ (note the caps) is defined in stdio.h already. I can't guarantee what size it is set to, open your stdio.h file and have a look for it.

OOPS! I jumped to the conclusion that it was something I had to deal with since you included it in your example. There I go asuming again! I will look at it as soon as get back to my linux box. If it were not for Linux I would not have a stdio.h to look in to.

Thanks!
