3559
3560 usri11_home_dir points to a null terminated ASCII string that contains
3561 the path name of the user's home directory.

3563 usri11_parms points to a null terminated ASCII string that is set
3564 aside for use by applications.
3565
3566 usri11_last_logon specifies the time when the user last logged on.

3569
3570 usri11_last_logoff specifies the time when the user last logged off.
3571 This value is stored as the number of seconds elapsed since
3572 00:00:00, January 1, 1970. A value of 0 means the last logoff
3573 time is unknown.

3575 usri11_bad_pw_count specifies the number of incorrect passwords
3576 entered since the last successful logon.

3578 usri11_log1_num_logons specifies the number of times this user has
3579 logged on. A value of -1 means the number of logons is unknown.
3580
3581 usri11_logon_server points to a null terminated ASCII string that
3582 contains the name of the server to which logon requests are sent.
3583 A null string indicates logon requests should be sent to the

3591 There may be up to 8 workstations, with the names separated by
3592 commas. A null strings indicates there are no restrictions.
3593
3594 usri11_max_storage specifies the maximum amount of disk space the user
3595 can occupy. A value of 0xffffffff indicates there are no
3596 restrictions.
3597
3598 usri11_units_per_week specifies the equal number of time units into
3599 which a week is divided. This value must be equal to 168.
3600
3601 usri11_logon_hours points to a 21 byte (168 bits) string that
3602 specifies the time during which the user can log on. Each bit
3603 represents one unique hour in a week. The first bit (bit 0, word
3604 0) is Sunday, 0:00 to 0:59, the second bit (bit 1, word 0) is
