Rerouting stdin and stdout from C

Question

I want to reopen the stdin and stdout (and perhaps stderr while I\'m at it) filehandles, so that future calls to printf()

Answer 1

This is a modified version of Tim Post's method; I used /dev/tty instead of /dev/stdout. I don't know why it doesn't work with stdout (which is a link to /proc/self/fd/1):

freopen("log.txt","w",stdout);
...
...
freopen("/dev/tty","w",stdout);

By using /dev/tty the output is redirected to the terminal from where the app was launched.

Hope this info is useful.
