- _S_e_t_p_g_r_p sets the process group of the specified process _p_i_d
- to the specified _p_g_r_p. If _p_i_d is zero, then the call
- applies to the current process.
-
- If the invoker is not the super-user, then the affected pro-
- cess must have the same effective user-id as the invoker or
- be a descendant of the invoking process.
