    rgid);
setruid() function
  (setrgid()) sets the real user ID (group ID) of the
  current process.
If the user is not the super user, or the uid specified is not the real or effective ID, these functions return -1.
The use of these calls is not portable. Their use is discouraged; they will be removed in the future.
setruid() and setrgid()
  syscalls appeared in 4.2BSD and were dropped in
  4.4BSD.
