       struct group *getgrnam(const char *name);

       struct group *getgrgid(gid_t gid);

DESCRIPTION
       The getgrnam() function returns a pointer to a structure containing the

                      char    *gr_passwd;      /* group password */
                      gid_t   gr_gid;          /* group id */
                      char    **gr_mem;        /* group members */
              };

       The  getgrnam()  and  getgrgid() functions return the group information
       structure, or NULL if the matching entry  is  not  found  or  an  error
       occurs.
