Module Name:

    winntsif.c

Abstract:

    winntsif.c is responsible for filling in the nt setup answer file with data from
    the win9xupg system being upgraded. This data is then used during unattended setup
    to control the installation of various portions of the winnt system.

    This is a rewrite and rationalization of the old unattend.c file.

Macro Expansion List Description:

  WINNTSIF_SECTIONS lists all of the sections in winnt.sif that will be populated by the
  winntsif processing code. The engine will enumerate each section in this list and then
  process the settings associated with that section.



Line Syntax:

   STRSECTION(SectionName,SettingsList)
   FUNSECTION(SectionFunction,SettingsList)

Arguments:

   SectionName - This is a string containing the name of the section that is processed.

   SectionFunction - This is an enumeration function that is called for sections that will
                     have multiple instances. This function returns a new section name each
                     time it is called, until there are no more instances to process.
                     At that time, this function returns NULL, ending the processing if the
                     associated section settings.

   SettingsList    - A list of settings associated with each function. Each of these settings
                     will be processed for the given section (or multiple sections in the case
                     of FUNSECTION lines..) See the description of the <X>_SECTION_SETTINGS
                     macro for more details on these settings.

Macro Expansion List Description:

  <X>_SECTION_SETTINGS lists the settings to be processed for the section X. Each section in the
  WINNTSIF_SECTIONS macro above contains a list of these settings..

Line Syntax:

   FUNDATA(CreationFunction,SettingName,DataFunction)
   STRDATA(CreationFunction,SettingName,DataString)
   REGDATA(CreationFunction,SettingName,RegKey,RegValue)


Arguments:

   CreationFunction - This is an optional boolean function which returns TRUE if the setting should
                      be written, FALSE if it should be skipped.

   SettingName      - A string containing the name of the setting being processed.

   DataFunction     - A Function which returns the string data to be written for the specified setting,
                      or NULL if nothing is to be written.

   DataString       - The actual string to write for the data of the setting.

   RegKey/RegValue  - The Key and value to use to retrieve the data to be written for the setting from
                      the registry.

Variables Generated From List:

   Used with WINNTSIF_SECTIONS to generate g_SectionList.

Routine Description:

  pGetRegistryValue is a utility wrapper used for getting data out of the
  registry. Because winntsif processing requires frequent and very similar
  reads from the registry, this wrapper is modified to be a little friendlier
  to this type of processing than the normal functions in reg.h. This
  function reads the data from the registry, and packs it into a multisz. It
  is capable of handling REG_DWORD, REG_MULTI_SZ, and REG_SZ style registry
  data. The data is stored in g_TempBuffer as well as being passed back
  through the return value. If the specified Key/Value does not exist in the
  registry, or the function is unable to retrieve a value, NULL is returned.

Arguments:

  KeyString   - Contains the Key to be read from the registry.
  ValueString - Contains the Value to be read from the registry.

Return Value:

  A pointer to a multisz containing the data if it could be read from the
  registry, NULL otherwise.

Routine Description:

  pEnumFirstAdapterByBinding and pEnumNextAdapterByBinding are memdb enumeration wrapperz

Arguments:

  Enum    - A pointer to a valid MEMDB_ENUM structure.
  Binding - Contains the binding to enumerate upon.

Return Value:

  TRUE if an adapter was found with the specified binding, FALSE otherwise.

Routine Description:

  Each Creation function is responsible for determining wether a specific
  winntsif setting should be processed or
  not. The purpose of most of these functions is obvious.

    pIsNetworkingInstalled -
        returns TRUE if the machine has networking installed.

    pIsNetBeuiInstalled -
        TRUE if NETBEUI is installed on the machine.

    pIsMsDlcInstalled -
        TRUE if MSDLC or MSDLC32 is installed on the machine.

    pIsNwIpxInstalled -
        TRUE if the machine is running the IPX protocol.

    pIsTcpIpInstalled -
        TRUE if the machine is running the TCPIP protocol.

    pIsDnsEnabled -
        TRUE DNS support is enabled.

    pIsRasInstalled
        TRUE if the machine uses Remote Access.

    pIsWkstaInstalled
        TRUE if the Workstation Service is installed.

    pIsNwClientInstalled
        TRUE if the NWLINK is installed.

    pHasStaticIpAddress
        TRUE if the machine has a static IP address.


Arguments:

  None.

Return Value:

  TRUE if the winntsif engine should process the setting, FALSE otherwise.
