fputs help

Hi all. The just of my program is that it catches a SIGINT signal and then writes something to a file. It writes it to the file the first time ok, but the second time it doesn't write. i even tried to fflush it and it still gives me the same problem.

here's a snipper of my code.

Code:

printf("Record Created\n");
      strcat(inputName," | ");
      strcat(address, " | ");
      strcat(phone, " | ");
printf("%s\n",inputName);
printf("%s\n",address);
printf("%s\n",phone);
      fflush(in);
      fputs(inputName,in);
      fputs(address,in);
      fputs(phone,in);
      close(fildes[0]);
      write(fildes[1],"New Record",30);
      write(fildes[1],inputName,30);
      write(fildes[1],"Record Created",30);
      //close(fildes[1]);
      fflush(in);

Could someone give me some suggestions on how to go about fixing it? Thanks!

Code:

 fflush(in);

I'll assume in is an input stream. As such, you can not flush input streams, only output. Flushing input streams is undefined behaviour.

It's odd that you call it 'in', if it is actually output. You'll definately want to rename that, because it makes your code unreadable and annoying to debug.

Otherwise, you'll have to post more code, so I don't have to play guessing games as to what all of your variables are.

A SIGINT is an interrupt, or rather, it usually means someone's entered an interrupt key on a terminal.

Quzah.

Dai-Lo.

You mention the problem is with signal handling yet you've not
shown how you handle the signal.

At a guess, do you reset the signal handler after the first interrupt.
