DESCRIPTION

		      char    *pw_name;	      /* user name */
		      char    *pw_passwd;     /* user password */
		      uid_t   pw_uid;	      /* user ID */
		      gid_t   pw_gid;	      /* group ID */
		      char    *pw_gecos;      /* real name */
		      char    *pw_dir;	      /* home directory */
		      char    *pw_shell;      /* shell program */
	      };
