SetupInstallFilesFromInfSection  6K9PMY 

[New - Windows NT]

The SetupInstallFilesFromInfSection function queues all the files in an INF file Copy Files94WX0. section to be installed.

BOOL SetupInstallFilesFromInfSection(

Parameters

InfHandle

Specifies a handle to an INF file that contains the section to be installed. The INF file must be a Windows 95- or Windows NT 4.0-style INF file; script-based INF files are not supported by SetupInstallFilesFromInfSection.

LayoutInfHandle

This optional parameter supplies a handle to the INF file that contains the SourceDisksFiles3.PG0KP and SourceDisksNames8OLI7ZO sections. If LayoutInfHandle is not specified, then the SourceDisksFiles and SourceDisksNames sections from InfHandle will be used.

FileQueue

Supplies a handle to the queue to add installation operations to.

SectionName

Supplies the name of the section in InfHandle to operate on.

SourceRootPath

This optional parameter specifies a root path to the source files to copy. An example would be A:\ or \\pegasus\win\install.

CopyFlags

This optional parameter specifies a set of flags that control the behavior of the file copy operation. These flags may be a combination of the following values:

SP_COPY_DELETESOURCE

Delete the source file upon successful copy. The caller is not notified if the delete fails.

SP_COPY_REPLACEONLY

Copy the file only if doing so would overwrite a file at the destination path.

SP_COPY_NEWER

Examine each file being copied to see if its version resources indicate that it is not newer than an existing copy on the target.

The file version information used during version checks is that specified in the dwFileVersionMS and dwFileVersionLS members of a VS_FIXEDFILEINFO0ICGL structure, as filled in by the Win32 version functions. If one of the files does not have version resources, or if they have identical version information, the source file is considered newer.

If the source file is not newer, and CopyMsgHandler is specified, the caller is notified and may cancel the copy. If CopyMsgHandler is not specified, the file is not copied.

SP_COPY_NOOVERWRITE

Check whether the target file exists, and, if so, notify the caller who may veto the copy. If CopyMsgHandler is not specified, the file is not overwritten.

SP_COPY_NODECOMP

Do not decompress the file. When this flag is set, the target file is not given the uncompressed form of the source name (if appropriate). For example, copying f:\mips\cmd.ex_ to \\install\temp results in a target file of \\install\temp\cmd.ex_. If the SP_COPY_NODECOMP flag was not specified, the file would be decompressed and the target would be called \\install\temp\cmd.exe. The filename part of DestinationName, if specified, is stripped and replaced with the filename of the source file. When SP_COPY_NODECOMP is specified, SP_COPY_LANGUAGEAWARE and SP_COPY_NEWER are ignored.

SP_COPY_LANGUAGEAWARE

Examine each file being copied to see if its language differs from the language of any existing file already on the target. If so, and CopyMsgHandler is specified, the caller is notified and may cancel the copy. If CopyMsgHandler is not specified, the file is not copied.

SP_COPY_SOURCE_ABSOLUTE

SourceFile is a full source path. Do not look it up in the SourceDisksNames section of the INF file.

SP_COPY_SOURCEPATH_ABSOLUTE

SourcePathRoot is the full path part of the source file. Ignore the relative source specified in the SourceDisksNames section of the INF file for the source media where the file is located. This flag is ignored if SP_COPY_SOURCE_ABSOLUTE is specified.

SP_COPY_FORCE_IN_USE

If the target exists, behave as if it is in use and queue the file for copying on the next system reboot.

SP_COPY_IN_USE_NEEDS_REBOOT

If the file was in use during the copy operation, alert the user that the system needs to be rebooted.

SP_COPY_NO_SKIP

Do not give the user the option to skip a file.

SP_COPY_FORCE_NOOVERWRITE

Check whether the target file exists, and, if so, the file is not overwritten. The caller is not notified.

SP_COPY_FORCE_NEWER

Examine each file being copied to see if its version resources (or timestamps for non-image files) indicate that it is not newer than an existing copy on the target. If the file being copied is not newer, the file is not copied. The caller is not notified.

SP_COPY_WARNIFSKIP

If the user tries to skip a file, warn them that skipping a file may affect the installation. (Used for system-critical files.)

Return Values

If the function succeeds, the return value is TRUE.

If the function fails, the return value is FALSE. To get extended error information, call GetLastError11C2VS7.

Remarks

SetupInstallFilesFromInfSection can be called multiple times to queue the files specified in multiple INF sections. After the queue has been successfully committed and the files have been copied, renamed, and/or deleted, SetupInstallFromInfSection can be called to perform registry and INI installation operations.

If a UNC directory is specified as the target directory of a file installation, you must ensure it exists before you call SetupInstallFilesFromInfSection. The setup functions do not check for the existence of and do not create UNC directories. If the target UNC directory does not exist, the file installation will fail.
