Valgrind `--track-fds = yes` without fds 0,1,2

Question

I run valgrind with the following setting: valgrind --tool=memcheck --tool=callgrind --num-callers=20 --track-fds=yes --error-exitcode=1 CMD . Especially, --track-fds=yes works as desired, but each run will fail due to fds 0,1,2 that need to be opened. However, I do not want to drop --track-fds , as it certainly provides meaningful information. So, is there a valgrind option / method for tracking fds, excluding 0,1,2?

Answer 1

These are stdin , stdout and stderr . You can usually ignore them, but if you really want to be squeamish:

fclose (stdin);
fclose (stdout);
fclose (stderr);
