Top Forums Programming what would happen if a process wrote to its own stdin? Post 302302007 by Perderabo on Sunday 29th of March 2009 06:44:23 PM

It wrote to stdin, aka file descriptor 0. You can add:
close(1);
close(2);
in front of your "if" statement to help prove it.

In this case, the shell opened /dev/tty for reading and writing and made all three initial fd's point to it.

Try:
echo hello > file
./a.out < file
echo who knows | ./a.out
