where:

  usri11_name specifies the user name for which information is retrieved

  usri11_pad aligns the next data structure element to a word boundary

  usri11_comment is a null terminated ASCII comment

  usri11_user_comment is a null terminated ASCII comment about the user

  usri11_priv specifies the level of the privilege assigned to the user.
       The possible values are:

Name             Value  Description
USER_PRIV_GUEST  0      Guest privilege
USER_PRIV_USER   1      User privilege
USER_PRV_ADMIN   2      Administrator privilege

  usri11_auth_flags specifies the account operator privileges. The
       possible values are:

Name            Value   Description
AF_OP_PRINT     0       Print operator

AF_OP_COMM      1       Communications operator
AF_OP_SERVER    2       Server operator
AF_OP_ACCOUNTS  3       Accounts operator


  usri11_password_age specifies how many seconds have elapsed since the
       password was last changed.

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

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

  usri11_last_logon specifies the time when the user last logged on.
       This value is stored as the number of seconds elapsed since
       00:00:00, January 1, 1970.

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

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

  usri11_log1_num_logons specifies the number of times this user has
       logged on. A value of -1 means the number of logons is unknown.

  usri11_logon_server points to a null terminated ASCII string that
       contains the name of the server to which logon requests are sent.
       A null string indicates logon requests should be sent to the
       domain controller.

  usri11_country_code specifies the country code for the user's language
       of choice.

  usri11_workstations points to a null terminated ASCII string that
       contains the names of workstations the user may log on from.
       There may be up to 8 workstations, with the names separated by
       commas. A null strings indicates there are no restrictions.

  usri11_max_storage specifies the maximum amount of disk space the user
       can occupy. A value of 0xffffffff indicates there are no
       restrictions.

  usri11_units_per_week specifies the equal number of time units into
       which a week is divided. This value must be equal to 168.

  usri11_logon_hours points to a 21 byte (168 bits) string that
       specifies the time during which the user can log on. Each bit
       represents one unique hour in a week. The first bit (bit 0, word
       0) is Sunday, 0:00 to 0:59, the second bit (bit 1, word 0) is

       Sunday, 1:00 to 1:59 and so on. A null pointer indicates there
       are no restrictions.

  usri11_code_page specifies the code page for the user's language of
       choice

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

There is no auxiliary data in the response.
