- Do not write functions that clobber call-by-reference variables on
failure. Use temporary variables for these cases and change the
passed in variables only on success.
- When you allocate a file descriptor, it should be made O_CLOEXEC
right from the beginning, as none of our files should leak to forked
binaries by default. Hence, whenever you open a file, O_CLOEXEC must
be specified, right from the beginning.
