  Not sure I understand your question. If we agree on using return values then 
there is only one way to do that. E.g. chmod() returns 0 on success, so the 
code could be like
    if (chmod(...) == 0)
         return reply;
  which jumps to the if (errno) code when chmod returns non-zero.
  Same for all other methods, check the man page for each to avoid making any 
assumptions, but presumably they all return 0 on success.
