Thread: Redirecting stdin - freopen alternative

I'm currently redirecting in a non-portable manner the standard input as:

Code:

freopen ("/dev/tty", "r", stdin);

which /dev/tty always points to the user's terminal. This helps me to read from input in a non-blocking manner.

I can perform well something like:

Code:

  while(fgets(buf, sizeof(buf), stdin))
    fputs(buf, stdout);

  freopen("/dev/tty", "rw", stdin);
  // continue with the rest of the code in a non-blocking manner

I'm wondering what would be an alternative to freopen, perhaps using I/O multiplexing. such as select()? or a thread that blocks on reading stdin?

Any alternative sample code would be appreciated.

Platforms: BSDs, Linux

Could you elaborate a little bit more about using select() instead of freopen? Or how would that apply on the above case? Thanks for your reply.
