Routine Description:

    Create a directory.  All containing directories are created to ensure
    that the directory can be created.  For example, if the directory to be
    created is \a\b\c, then this routine will create \a, \a\b, and \a\b\c
    in that order.

Arguments:

    DevicePath - supplies pathname to the device on which the directory
        is to be created.

    RootDirectory - if specified, supplies a fixed portion of the directory name,
        which may or may not have been already created. The directory being created will be
        concatenated to this value.

    Directory - supplies directory to be created on the device. You may use
        this to specify a full NT path (pass in NULL for DevicePath and
        RootDirectory).

Return Value:

    None.  Does not return if directry could not successfully be created.

    the remote boot server, and if it does, create a single-instance store
    link to the existing file instead of doing the copy.

Arguments:

    SourceFilename - supplies fully qualified name of file

    TargetFilename - supplies fully qualified name of file
        in the NT namespace.

    TargetAttributes - if supplied (ie, non-0) supplies the attributes

Routine Description:

    Calculate a checksum value for a file using the standard
    nt image checksum method.  If the file is an nt image, validate
    the image using the partial checksum in the image header.  If the
    file is not an nt image, it is simply defined as valid.

    If we encounter an i/o error while checksumming, then the file
    is declared invalid.

Arguments:

    FileHandle - supplies handle of file to check (if not present, then
        Filename specifies the file to be opened and checked)

    Filename - supplies full NT path of file to check (if not present, then
        FileHandle must be specified)

    IsNtImage = Receives flag indicating whether the file is an
        NT image file.

    Checksum - receives 32-bit checksum value.

    Valid - receives flag indicating whether the file is a valid
        image (for nt images) and that we can read the image.

Return Value:

    None.

Routine Description:

    This routine copies a single file, allowing retry is an error occurs
    during the copy.  If the source file is LZ compressed, then it will
    be decompressed as it is copied to the target.

    If the file is not successfully copied, the user has the option
    to retry to copy or to skip copying that file after a profuse warning
    about how dangerous that is.

Arguments:

    FileToCopy - supplies structure giving information about the file
        being copied.

    SourceDevicePath - supplies path to device on which the source media
        is mounted (ie, \device\floppy0, \device\cdrom0, etc).

    DirectoryOnSourceDevice - Supplies the directory on the source where
        the file is to be found.

    TargetRoot - if specified, supplies the directory on the target
        to which the file is to be copied.

    TargetFileAttributes - if supplied (ie, non-0) supplies the attributes
        to be placed on the target on successful copy (ie, readonly, etc).
        If not specified, the attributes will be set to FILE_ATTRIBUTE_NORMAL.

    DrawScreen - supplies address of a routine to be called to refresh
        the screen.

    FileCheckSum - if specified, will contain the check sum of the file copied.

    FileSkipped - if specified, will inform the caller if there was no attempt
                  to copy the file.

    Flags - supplies flags to control special processing for this file, such as
        deleting the source file on successful copy or skip; smashing locks;
        specifying that the source file is oem; or to indicate that en oem file
        with the same name should be overwritten on upgrade. This value is ORed
        in with the Flags field of FileToCopy.

Return Value:

    None.

Routine Description:

    Iterate the copy list for each setup source disk and prompt for
    the disk and copy/decompress all the files on it.

Arguments:

    SifHandle - supplies handle to setup information file.

    DiskFileLists - supplies the copy list, in the form of an array
        of structures, one per disk.

    DiskCount - supplies number of elements in the DiskFileLists array,
        ie, the number of setup disks.

    SourceDevicePath - supplies the path of the device from which files
        are to be copied (ie, \device\floppy0, etc).

    DirectoryOnSourceDevice - supplies the directory on the source device
        where files are to be found.

    TargetRoot - supplies root directory of target.  All target directory
        specifications are relative to this directory on the target.

    CompatibilityExceptionList - Singly-linked list of
        PINCOMPATIBLE_FILE_ENTRY objects that should be skipped during
        copying.  Optional, pass NULL if no exceptions are present.

Return Value:

    None.

Routine Description:

    that contains FileName and TargetMediaPath.  If TargetMediaPath is not
    specified, indicates TRUE if a member with the name FileName is listed
    instead.  (Dangerous.)

Arguments:

    FileList - Header node of a list created with

    pFile - File to copy structure, containing all the relevant information

    FALSE otherwise, or if FileList or FileName is NULL.

Remarks:

    This routine could be made more robust in the face of bad parameters,
    but this was deemed superfluous, since there's exactly one caller of
    this API whose values are already checked.  This function will then
    behave "properly" in all cases.

Routine Description:

    Initialize disk file lists.  This involves looking in a given section
    in the sectup information file and fetching information for each
    disk specified there.  The data is expected to be in the format

    [<SifSection>]
    <MediaShortname> = <Description>,<TagFile>[,,<Directory>]
    ...


    (Note that <Directory> is the third field -- the 2 commas
    are not a typo -- field 2 is unused.)

Arguments:

    SifHandle - supplies handle to loaded setup information file.

    DiskFileLists - receives pointer to an array of disk file list
        structures, one per line in SifSection.  The caller must free
        this buffer when finished with it.

    DiskCount - receives number of elements in DiskFileLists array.

Return Value:

    None.

        into which the file will be copied.

    TargetFilename - supplies the name of the file as it will exist
        in the target tree.

    TargetDevicePath - supplies the NT name of the device onto which the file
        is to be copied (ie, \device\harddisk1\partition2, etc).

    AbsoluteTargetDirectory - indicates whether TargetDirectory is a path from the
        root, or relative to a root to specified later.

Routine Description:

    Adds a single file to the list of files to be copied.

    The file, along with the directory into which it is to be copied
    n the target and the name it is to receive on the target, is listed
    in a section in the setup information file.

    The filename is used to index the master file list to determine the
    source media where it resides.

    All this information is recorded in a structure associated with
    the disk on which the file resides.

    [SpecialFiles]
    mpkernel = ntkrnlmp.exe,4,ntoskrnl.exe
    upkernel = ntoskrnl.exe,4,ntoskrnl.exe
    etc.

    [MasterFileList]
    ntkrnlmp.exe = d2
    ntoskrnl.exe = d3
    etc.

Arguments:

    SifHandle - supplies handle to loaded setup information file.

    DiskFileLists - supplies an array of file lists, one for each distribution
        disk in the product.

    DiskCount - supplies number of elements in the DiskFileLists array.

    SifSection - supplies the name of the section that lists the file
        being added to the copy list.

    SifKey - if specified, supplies the keyname for the line in SifSection
        that lists the file to be added to the copy list.

    SifLine - if SifKey is not specified, this parameter supplies the 0-based
        line number of the line in SifSection that lists the file to be added
        to the copy list.

    TargetDevicePath - supplies the NT name of the device onto which the file
        is to be copied (ie, \device\harddisk1\partition2, etc).

    TargetDirectory - If specified, supplies the directory into which the file
        is to be copied on the target; overrides the value specified on the line
        in SifSection.  This allows the caller to specify an absolute directory
        for the file instead of using indirection.

    CopyOptions -
         COPY_ALWAYS              : always copied
         COPY_ONLY_IF_PRESENT     : copied only if present on the targetReturn Value:

         COPY_NEVER               : never copied                            None.

    CheckForNoComp - if true, check this file to see if it must remain uncompressed
        on an NTFS system partition supporting compression.
        If so, then OR the CopyOptions value with COPY_FORCENOCOMP.

Return Value:

    None.

Routine Description:

    Adds files listed in a setup information file section to the copy list.

    Each line in the section is expected to be in a standard format:

    [Section]
    <source_filename>,<target_directory_shortname>[,<target_filename>]

Arguments:

    SifHandle - supplies handle to loaded setup information file.

    DiskFileLists - supplies an array of file lists, one for each distribution
        disk in the product.

    DiskCount - supplies number of elements in the DiskFileLists array.

    SectionName - supplies the name of the section that lists the files
        being added to the copy list.

    TargetDevicePath - supplies the NT name of the device onto which the files
        are to be copied (ie, \device\harddisk1\partition2, etc).

    TargetDirectory - If specified, supplies the directory into which the files
        are to be copied on the target; overrides values specified on the lines
        in [<SectionName>].  This allows the caller to specify an absolute directory
        for the files instead of using indirection via a target directory shortname.

    CopyOptions -
         COPY_ALWAYS              : always copied
         COPY_ONLY_IF_PRESENT     : copied only if present on the targetReturn Value:
         COPY_ONLY_IF_NOT_PRESENT : not copied if present on the target
         COPY_NEVER               : never copied

    CheckForNoComp - if true, then check each file to see if it must exist uncompressed
        on an NTFS partition supporting compression (ie, NTLDR on x86).

Routine Description:

    Create c:\ntbootdd.sys if necessary.

    The scsi miniport driver file will be copied from the drivers directory
    (where it was copied during the earlier file copy phase) to c:\ntbootdd.sys.

    In the atapi case, the file ataboot.sys will be copied from the media to
    c:\ntbootdd.sys.

    NOTE: We're not going to support this on atapi devices anymore.  However,
    I'm leaving the code here in case we want to do it again later.  This code
    should execute early because I've modifed SpGetDiskInfo, so that
    ScsiMiniportShortname won't ever get set for atapi devices. -matth

Arguments:

    NtPartitionRegion - supplies the region descriptor for the disk region
        onto which the user chose to install Windows NT.

    NtPartitionDevicePath - supplies the nt namespace pathname for the
        partition onto which the user chose to install Windows NT.

    Sysroot - supplies the directory on the target partition.

    SystemPartitionDevicePath - supplies the nt device path of the partition
        onto which to copy ntbootdd.sys (ie, C:\).

    SifHandle - supplies handle to loaded setup information file.

    SourceDevicePath- Path to the device that contains the source.

    DirectoryOnSourceDevice - Supplies the directory on the source where
        the file is to be found.

Routine Description:

    Removes an entry from a disk's file copy list.

Arguments:

    DiskFileLists - supplies an array of file lists, one for each distribution
        disk in the product.

    DiskCount - supplies number of elements in the DiskFileLists array.

    TargetDirectory - supplies the directory on the target media
        into which the file will be copied.

    TargetFilename - supplies the name of the file as it will exist
        in the target tree.

    TargetDevicePath - supplies the NT name of the device onto which the file
        is to be copied (ie, \device\harddisk1\partition2, etc).

    AbsoluteTargetDirectory - indicates whether TargetDirectory is a path from the
        root, or relative to a root to specified later.

Return Value:

    TRUE if a new copy list entry was created; FALSE if not (ie, the file was
        already on the copy list).
