- The real and effective group ID's of the current process are set to the
- arguments. Unprivileged users may change the real group ID to the
- effective group ID and vice-versa; only the super-user may make other
- changes.
-
- Supplying a value of -1 for either the real or effective group ID forces
- the system to substitute the current ID in place of the -1 parameter.

- Upon successful completion, a value of 0 is returned. Otherwise, a value
- of -1 is returned and _e_r_r_n_o is set to indicate the error.

- [EPERM] The current process is not the super-user and a change
