Hello everybody... In my client - server application I decided to save user name and password in a file by the system call creat(), write().
Now there is a problem in the client-autentication and the next registration-autentication becouse I don't know very well how to manage the file:
This is the autentication code but it's not work
where the problem?? is there someone that has got some good example with I/O file?? For example if I want to start reading or writing not at the begin but for example in the middle of the file or in the second row or at the fifth word???
Thank you very much!
This line:
...what is it even supposed to do? I can't tell. It looks vaguely like a function call but there's no function! I'm shocked it compiles.
For file I/O, see man pages for fopen, fclose, and fgets. if it's a text file it's best to read line by line since you'll have no idea what line you'll end up in when you seek.
