3553
3554 usri11_password_age specifies how many seconds have elapsed since the
3555 password was last changed.
3556
3557 usri11_home_dir points to a null terminated ASCII string that contains
3558 the path name of the user's home directory.

3560 usri11_parms points to a null terminated ASCII string that is set
3561 aside for use by applications.

3563 usri11_last_logon specifies the time when the user last logged on.

3565 00:00:00, January 1, 1970.
3566
3567 usri11_last_logoff specifies the time when the user last logged off.
3568 This value is stored as the number of seconds elapsed since
3569 00:00:00, January 1, 1970. A value of 0 means the last logoff
3570 time is unknown.

3572 usri11_bad_pw_count specifies the number of incorrect passwords
3573 entered since the last successful logon.

3575 usri11_log1_num_logons specifies the number of times this user has
3576 logged on. A value of -1 means the number of logons is unknown.
3577
3578 usri11_logon_server points to a null terminated ASCII string that
3579 contains the name of the server to which logon requests are sent.
3580 A null string indicates logon requests should be sent to the
3581 domain controller.
3582
3583 usri11_country_code specifies the country code for the user's language

3586 usri11_workstations points to a null terminated ASCII string that
3587 contains the names of workstations the user may log on from.
3588 There may be up to 8 workstations, with the names separated by
3589 commas. A null strings indicates there are no restrictions.
3590
3591 usri11_max_storage specifies the maximum amount of disk space the user
3592 can occupy. A value of 0xffffffff indicates there are no
3593 restrictions.
3594
3595 usri11_units_per_week specifies the equal number of time units into
3596 which a week is divided. This value must be equal to 168.
3597
3598 usri11_logon_hours points to a 21 byte (168 bits) string that
3599 specifies the time during which the user can log on. Each bit
3600 represents one unique hour in a week. The first bit (bit 0, word
3601 0) is Sunday, 0:00 to 0:59, the second bit (bit 1, word 0) is

3616 choice
3617
3618 All of the pointers in this data structure need to be treated
3619 specially. The pointer is a 32 bit pointer. The higher 16 bits need
3620 to be ignored. The converter word returned in the parameters section
3621 needs to be subtracted from the lower 16 bits to calculate an offset
3622 into the return buffer where this ASCII string resides.
