Redirection stdout with low level api in C

Question

Is there a way to redirect stdout with low level API... haven't found a function or a way to actually do this....

Answer 1

The dup system call should let you redirect stdout, as shown in this example.

freopen also will work, if you're redirecting to a file, but dup can also be used with pipes and sockets.

Answer 2

I believe dup2(fd,1) does the trick, e.g. after opening fd using open().
