       The  putgrent()  function  is  the  counterpart for fgetgrent(3).  The function writes the content of the
       provided structgroup into the stream.  The list of  group  members  must  be  NULL-terminated  or  NULL-
       initialized.

       The structgroup is defined as follows:

           struct group {
               char   *gr_name;      /* group name */
               char   *gr_passwd;    /* group password */
               gid_t   gr_gid;       /* group ID */
               char  **gr_mem;       /* group members */
           };
