3883 usri11_home_dir points to a null terminated ASCII string that contains
3884 the path name of the user's home directory.
3885
3886 usri11_parms points to a null terminated ASCII string that is set
3887 aside for use by applications.
3888
3889 usri11_last_logon specifies the time when the user last logged on.
3890 This value is stored as the number of seconds elapsed since
3891 00:00:00, January 1, 1970.
3892
3893 usri11_last_logoff specifies the time when the user last logged off.
3894 This value is stored as the number of seconds elapsed since
3895 00:00:00, January 1, 1970. A value of 0 means the last logoff
3896 time is unknown.
3897
3898 usri11_bad_pw_count specifies the number of incorrect passwords
3899 entered since the last successful logon.
3900
3901 usri11_log1_num_logons specifies the number of times this user has
3902 logged on. A value of -1 means the number of logons is unknown.
3903
3904 usri11_logon_server points to a null terminated ASCII string that
3905 contains the name of the server to which logon requests are sent.
3906 A null string indicates logon requests should be sent to the
3907 domain controller.
3908
3909 usri11_country_code specifies the country code for the user's language
3910 of choice.
3911
3912 usri11_workstations points to a null terminated ASCII string that
3913 contains the names of workstations the user may log on from.
3914 There may be up to 8 workstations, with the names separated by
3915 commas. A null strings indicates there are no restrictions.
3916
3917 usri11_max_storage specifies the maximum amount of disk space the user
3918 can occupy. A value of 0xffffffff indicates there are no
3919 restrictions.
3920
3921 usri11_units_per_week specifies the equal number of time units into
3922 which a week is divided. This value must be equal to 168.
3923
3924 usri11_logon_hours points to a 21 byte (168 bits) string that
3925 specifies the time during which the user can log on. Each bit
3926 represents one unique hour in a week. The first bit (bit 0, word
3927 0) is Sunday, 0:00 to 0:59, the second bit (bit 1, word 0) is

3938 Sunday, 1:00 to 1:59 and so on. A null pointer indicates there
3939 are no restrictions.
3940
3941 usri11_code_page specifies the code page for the user's language of
3942 choice
3943
3944 All of the pointers in this data structure need to be treated
3945 specially. The pointer is a 32 bit pointer. The higher 16 bits need
3946 to be ignored. The converter word returned in the parameters section
3947 needs to be subtracted from the lower 16 bits to calculate an offset
3948 into the return buffer where this ASCII string resides.
3949
3950 There is no auxiliary data in the response.
