Hi,
What are the safest POSIX.1 functions?
Asked from a different angle, what functions should one be wary of
with POSIX C programming?
What POSIX functions can be easily misused?

There was no inappropriate followup - that's a projection you've made
based on your own ridiculous prejudices. |

perror
puts
use with care
printf

unsafe:

exit() calls handlers registered with atexit(). Those could be doing
all manner of unsafe things. _exit(), on the other hand, goes
directly to the exit syscall. Nothing could be safer.
