Question

// Trying to read file


void readFilee(char *namefile){

    FILE *f_in = fopen(namefile,"r");
    char x;
    int i = 0;

    if(!f_in){ printf("Error"); exit(0); }

    /* read to EOF */
    while(1){
        x = getc(f_in);
        if(x == '\n') continue;
            archivo[i] = x;
        if(x == EOF) break;
            i++;
    }
    tamArchivo = i;
    fclose(f_in);
}

Fact that the error was f_in is null, but I do not understand why? I’m trying to connect a server with multiple clients, the clients are initialized waiting connection.

The command verificion “if” I get “Error”

Answer 1

add

archivo[i] = '\0';

after the while loop terminate. This will add null charachter at the end of your string archivo

also may be the memory space of your archivo array is not sufficient to get the whole content of the file and so it could cause a buffer overflow so it could cause a crash
