Yes - Just remember you must use fcntl(, F_DUPFD, ) not dup2().

Genious! I didn't know about that thing!
So you just dup the fd and close the old one right?
Thanks!

stdio struct used a char for the file descriptor.
If you have control over the file descriptors you application is
creating you can push them to higher numbers with
newfd = fcntl(orgfd, F_DUPFD, lowlimit);
leaving a range of low number file descriptors free to use for c-ares.
Yes it's ugly, but if nothing else helps...
