Routine Description:

    Place a copy operation on a setup file queue.

Arguments:

    QueueHandle - supplies a handle to a setup file queue, as returned
        by SetupOpenFileQueue.

    SourceRootPath - Supplies the root of the source for this copy,
        such as A:\ or \\FOO\BAR\BAZ.  If this parameter isn't supplied, then
        this queue node will be added to a media descriptor's queue that
        matches on SourceDescription and SourceTagfile.  (This merge will take
        place regardless of whether or not the media descriptor entry was
        already in the queue prior to calling SetupQueueCopy.)

        If there is no matching media descriptor that contains SourceRootPath
        information, the path will be set to the directory where the system was
        installed from.

    SourcePath - if specified, supplies the path relative to SourceRootPath
        where the file can be found.

    SourceFilename - supplies the filename part of the file to be copied.

    SourceDescription - if specified, supplies a description of the source
        media, to be used during disk prompts.

    SourceTagfile - if specified, supplies a tag file whose presence at
        SourceRootPath indicates the presence of the source media.
        If not specified, the file itself will be used as the tag file
        if required (tagfiles are used only for removable media).

    TargetDirectory - supplies the directory where the file is to be copied.

    TargetFilename - if specified, supplies the name of the target file.
        If not specified, the target file will have the same name as the source.

    CopyStyle - supplies flags that control the behavior of the copy operation
        for this file.

Return Value:

    Boolean value indicating outcome. If FALSE, GetLastError() returns
    extended error information.

Routine Description:

    Worker routine for SetupQueueCopy and friends.

Arguments:

    CopyParams - supplies a structure with information about the file
        to be queued. Fields are used as follows.

        cbSize - must be sizeof(SP_FILE_COPY_PARAMS). The caller should
            have verified this before calling this routine.

        QueueHandle - supplies a handle to a setup file queue, as returned
            by SetupOpenFileQueue.

        SourceRootPath - Supplies the root of the source for this copy,
            such as A:\ or \\FOO\BAR\BAZ.   If this field is NULL, then this
            queue node will be added to a media descriptor's queue that matches
            on SourceDescription and SourceTagfile.  (This merge will take
            place regardless of whether or not the media descriptor entry was
            already in the queue prior to calling SetupQueueCopy.)

            If there is no matching media descriptor that contains
            SourceRootPath information, the path will be set to the directory
            where the system was installed from.

        SourcePath - if specified, supplies the path relative to SourceRootPath
            where the file can be found.

        SourceFilename - supplies the filename part of the file to be copied.

        SourceDescription - if specified, supplies a description of the source
            media, to be used during disk prompts.

        SourceTagfile - if specified, supplies a tag file whose presence at
            SourceRootPath indicates the presence of the source media.
            If not specified, the file itself will be used as the tag file
            if required (tagfiles are used only for removable media).

        TargetDirectory - supplies the directory where the file is to be copied.

        TargetFilename - if specified, supplies the name of the target file.  If
            not specified, the target file will have the same name as the source.

        CopyStyle - supplies flags that control the behavior of the copy
            operation for this file.

        LayoutInf - supplies the handle to the inf which contains the source
            layout info for this file, if any.

    LayoutLineContext - if specified, this argument provides the INF context
        for the [SourceDisksFiles] entry pertaining to the file to be copied.
        If not specified, the relevant [SourceDisksFiles] entry will be searched
        for in the LayoutInf handle specified in the CopyParams structure.  This
        context must be contained within either the CopyParams->LayoutInf or
        AdditionalInfs loaded INF handles (because those are the two INFs we're
        gonna lock).  The argument is used to prevent us from having to search
        for the file to be copied in a [SourceDisksFiles] section.  The caller
        has already done that, and is either handing us the context to that INF
        entry, or has passed -1 to indicate that there is no [SourceDisksFiles]
        entry.

    AdditionalInfs - if specified, supplies an additional HINF (potentially
        containing multiple append-loaded INFs) that need to be added to our
        SPQ_CATALOG_INFO list for later validation.  Do not supply this parameter
        if it is identical to the value of the LayoutInf field in the CopyParams
        structure.

Return Value:

    Boolean value indicating outcome. If FALSE, GetLastError() returns
    extended error information.

Routine Description:

    Queue an entire section in an inf file for copy. The section must be
    in copy-section format and the inf file must contain [SourceDisksFiles]
    and [SourceDisksNames] sections.

Arguments:

    QueueHandle - supplies a handle to a setup file queue, as returned
        by SetupOpenFileQueue.

    SourceRootPath - supplies the root directory for the intended source.
        This should be a sharepoint or a device root such as a:\ or g:\.

    InfHandle - supplies a handle to an open inf file, that contains the
        [SourceDisksFiles] and [SourceDisksNames] sections, and, if
        ListInfHandle is not specified, contains the section names by Section.
        This handle must be for a win95-style inf.

    ListInfHandle - if specified, supplies a handle to an open inf file
        containing the section to be queued for copy. Otherwise InfHandle
        is assumed to contain the section.

    Section - supplies the name of the section to be queued for copy.

    CopyStyle - supplies flags that control the behavior of the copy operation
        for this file.

Return Value:

    Boolean value indicating outcome. If FALSE, GetLastError() returns
    extended error information. Some of the files may have been queued.

Routine Description:

    Add a single file to the copy queue, using the default source media
    and destination as specified in an inf file.

Arguments:

    QueueHandle - supplies a handle to a setup file queue, as returned
        by SetupOpenFileQueue.

    InfHandle - supplies a handle to an open inf file, that contains the
        [SourceDisksFiles] and [SourceDisksNames] sections.
        This handle must be for a win95-style inf.

    ListInfHandle - if specified, supplies handle to the inf in which
        the file being copied appears (such as in a file copy list section).
        If not specified, this is assumed to be the same inf as InfHandle.

    SourceRootPath - supplies the root directory for the intended source.
        This should be a sharepoint or a device root such as a:\ or g:\.

    SourceFilename - supplies the filename of the source file. Filename part
        only.

    TargetFilename - supplies the filename of the target file. Filename part
        only.

    CopyStyle - supplies flags that control the behavior of the copy operation
        for this file.

    SecurityDescriptor - describes the permissions for the target file

    CacheName - if supplied this is the name of the driver cache we should
                use to copy the file out of instead of the specified source path

Return Value:

    Boolean value indicating outcome. If FALSE, GetLastError() returns
    extended error information.

Routine Description:

    Add a single file to the copy queue, using the default source media
    and destination as specified in an inf file.

Arguments:

    QueueHandle - supplies a handle to a setup file queue, as returned
        by SetupOpenFileQueue.

    InfHandle - supplies a handle to an open inf file, that contains the
        [SourceDisksFiles] and [SourceDisksNames] sections.
        This handle must be for a win95-style inf.

    SourceRootPath - supplies the root directory for the intended source.
        This should be a sharepoint or a device root such as a:\ or g:\.

    SourceFilename - supplies the filename of the source file. Filename part
        only.

    TargetFilename - supplies the filename of the target file. Filename part
        only.

    CopyStyle - supplies flags that control the behavior of the copy operation
        for this file.

Return Value:

    Boolean value indicating outcome. If FALSE, GetLastError() returns
    extended error information.

Routine Description:

    Set up a file queue node's source media descriptor pointer, creating a new
    source media descriptor if necessary.

Arguments:

    Queue - supplies pointer to file queue with which the queue node
        is associated.

    QueueNode - supplies file queue node whose source media descriptor pointer
        is to be set.

    SourceRootStringId - supplies string id of root to source (something like a:\).

    SourceDescription - if specified, supplies a description for the media.

    SourceTagfile - if specified, supplies a tag file for the media.

    SourceCabfile - if specified, supplies a cabfile for the media different to the tagfile.

    MediaFlags - specifies additional information used in searching for an
        existing source media descriptor in the specified queue, and in adding
        new source media descriptors to that queue.  May be a combination of
        the following values:

        SMI_FLAG_NO_SOURCE_ROOT_PATH : The caller didn't supply a SourceRootPath
            for this copy action, so we're using a default path.  This flag
            causes us to not include the SourceRootStringId as part of our
            match criteria when searching to see if the specified source media
            information is already present in an existing media descriptor.  If
            we don't find a match (i.e., we have to create a new descriptor),
            we'll store this flag away in the SOURCE_MEDIA_INFO.Flags field so
            that if we come along later to add source media descriptors where
            the caller did specify SourceRootPath, then we'll re-use this
            descriptor and overwrite the existing (default) source root path
            with the caller-specified one.

        SMI_FLAG_USE_SVCPACK_SOURCE_ROOT_PATH : The caller didn't supply a SourceRootPath
            for this copy action, and it's a tagged source media, so we're using a
            service pack path.  This flag  causes us to not include the SourceRootStringId
            as part of our match criteria when searching to see if the specified source media
            information is already present in an existing media descriptor.  If
            we don't find a match (i.e., we have to create a new descriptor),
            we'll store this flag away in the SOURCE_MEDIA_INFO.Flags field so
            that if we come along later to add source media descriptors where
            the caller did specify SourceRootPath, then we'll re-use this
            descriptor and overwrite the existing (default) source root path
            with the caller-specified one.

        SMI_FLAG_USE_LOCAL_SOURCE_CAB : The caller wants to use the local source cab containing
            driver files, etc.  In this case, we supply the source description and tagfile,
            ignoring what the caller passes in.  At this point we know the media is present, as
            the caller provided this check.  If it wasnt't, we default to the OS Source path location.
            Mutually exclusive with SMI_FLAG_USE_LOCAL_SPCACHE

        SMI_FLAG_USE_LOCAL_SPCACHE : The caller wants to get files from the ServicePackCache
            directory. This is used to make hotfixes etc "sticky".


Return Value:

    Pointer to source media info structure, or NULL if out of memory.
