Описание (Description)

The putgrent() function is the counterpart for fgetgrent(3).  The

       stream.  The list of group members must be NULL-terminated or
       NULL-initialized.

       The struct group 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 */
           };
