Redirecting low-api stdout to C

Question

Is there a way to redirect stdout from a low level API ... did not find a function or way to do this ....

Answer 1

The system call dupshould allow you to redirect stdout, as shown in this example .

freopenwill also work if you are redirected to a file, but dupcan also be used with handsets and sockets.

Answer 2

I believe that dup2 (fd, 1) does the trick, for example. after opening fd with open ().

Answer 3

freopen(), .

Answer 4

You can use freopen()to redirect stdout to a file. If you are using a posix-like system, you can use close(), dup()and open()although they work with file descriptors, not files.
