3889 usri11_last_logoff specifies the time when the user last logged off.
3890 This value is stored as the number of seconds elapsed since
3891 00:00:00, January 1, 1970. A value of 0 means the last logoff
3892 time is unknown.
3893
3894 usri11_bad_pw_count specifies the number of incorrect passwords
3895 entered since the last successful logon.
3896
3897 usri11_log1_num_logons specifies the number of times this user has
3898 logged on. A value of -1 means the number of logons is unknown.
3899
3900 usri11_logon_server points to a null terminated ASCII string that
3901 contains the name of the server to which logon requests are sent.
3902 A null string indicates logon requests should be sent to the
3903 domain controller.
3904
3905 usri11_country_code specifies the country code for the user's language
3906 of choice.
3907
3908 usri11_workstations points to a null terminated ASCII string that
3909 contains the names of workstations the user may log on from.
3910 There may be up to 8 workstations, with the names separated by
3911 commas. A null strings indicates there are no restrictions.
3912
3913 usri11_max_storage specifies the maximum amount of disk space the user
3914 can occupy. A value of 0xffffffff indicates there are no
3915 restrictions.
3916
3917 usri11_units_per_week specifies the equal number of time units into
3918 which a week is divided. This value must be equal to 168.
3919
3920 usri11_logon_hours points to a 21 byte (168 bits) string that
3921 specifies the time during which the user can log on. Each bit
3922 represents one unique hour in a week. The first bit (bit 0, word
3923 0) is Sunday, 0:00 to 0:59, the second bit (bit 1, word 0) is

3935 Sunday, 1:00 to 1:59 and so on. A null pointer indicates there
3936 are no restrictions.
3937
3938 usri11_code_page specifies the code page for the user's language of
3939 choice
3940
3941All of the pointers in this data structure need to be treated
3942specially. The pointer is a 32 bit pointer. The higher 16 bits need
3943to be ignored. The converter word returned in the parameters section
3944needs to be subtracted from the lower 16 bits to calculate an offset
3945into the return buffer where this ASCII string resides.
3946
3947There is no auxiliary data in the response.
