Of course it's possible to archieve same thing without dup2(). POSIX specification for open() says: "The open() function shall return a file descriptor for the named file that is the lowest file descriptor not currently open for that process." So one should close(fileno(stdout)) and then open() file, which will return 1, as it's lowest free descriptor number, but probably using dup2() makes this more explicit.
