Simple C question (i think)

hey there people!
well, I've got here some code for a program I'm doing and was wondering if you could help me.

Code:

---

function disciplinas=ler_disciplinas(ficheiro)
        fid2=fopen(ficheiro,"r");
        xx=list();

        while !feof(fid2)
                a=ler_disciplina(fid2);
                xx=append(xx,a);
        endwhile

        fclose(fid2);

disciplinas=xx;

endfunction

---

well, the problem here is that to run this program i can read from 3 different files , "analise.txt", "computacao.txt" and "fisica.txt".

What I want is to, for ex., if I run :
ler_disciplinas("analise.txt")

all the read data is added to a list named analise.

If I run:
ler_disciplinas("computacao.txt")

all the read data is added to a list named computacao.

Now the program is always adding the data to the list "disciplinas", always overwriting...

So, can you guys help me?

thanks in advance

Look into opening the file with in append mode ("a" or "a+"). As for the rest, I don't think I really understand what this "disciplinas" file is, as I've only seen you mention the files analise, computacao and fisica...

disciplinas is just the name of the list i want to make.
if the user runs the program to read from analise.txt, i want the list to be named "analise" instead of "disciplinas"... the same works for computacao e fisica...

here is the analises.txt file:

what it does is read each line, make a structure for each one, and in the end add all of them to a list.

so what you want is that the program reads all these files and then puts all their data into another file called disciplinas ? Or is disciplinas just an array of some sort ?

no, the program reads the file chosen "analises.txt", "computacao.txt" or "fisica.txt" and then puts the read data in a list with the name of the file.
so, if i read "analise.txt" the list where the data is , is called "analise". and if I read "computacao.txt" i want the list to be called "computacao".

how can i do that?

Like

Code:

---

list analise, computacao;
if ( strcmp( filename, "analises.txt" ) == 0 ) {
  FILE *fp = fopen(filename,"r");
  while ( fgets( buff, sizeof buff, fp ) != NULL ) {
    append( &analise, buff );
  }
}
