SetupInstallFromInfSectionW function (setupapi.h)
[This function is available for use in the operating systems indicated in the Requirements section. It may be altered or unavailable in subsequent versions. SetupAPI should no longer be used for installing applications. Instead, use the Windows Installer for developing application installers. SetupAPI continues to be used for installing device drivers.]
The SetupInstallFromInfSection function carries out all the directives in an INF file Install section.
If the registry or file is modified, the caller of this function is required have privileges to write into the system or target directory.

Parameters
Owner
Optional pointer to the window handle to the window that owns any dialog boxes that are generated during installation, such as for disk prompting or file copying. If Owner is not specified, these dialog boxes become top-level windows.
InfHandle
Handle to the INF file that contains the section to be processed.
SectionName
Name of the Install section in the INF file to process.
Flags
Controls what actions to perform. The flags can be a combination of the following values.
SPINST_INIFILES
Perform INI-file operations (UpdateInis, UpdateIniFields lines in the Install section being processed).
SPINST_REGISTRY
Perform registry operations (AddReg, DelReg lines in the Install section being processed).
SPINST_INI2REG
Perform INI-file to registry operations (Ini2Reg lines in the Install section being processed).
SPINST_LOGCONFIG
This flag is only used when installing a device driver.
Perform logical configuration operations (LogConf lines in the Install section being processed). This flag is only used if DeviceInfoSet and DeviceInfoData are specified.
For more information about installing device drivers, LogConf, DeviceInfoSet, or DeviceInfoData, see the DDK Programmer's Guide.
SPINST_FILES
Perform file operations (CopyFiles, DelFiles, RenFiles lines in the Install section being processed).
SPINST_ALL
Perform all installation operations.
SPINST_REGISTERCALLBACKAWARE
When using the RegisterDlls INF directive to self-register DLLs on Windows 2000, callers of SetupInstallFromInfSection may receive notifications on each file as it is registered or unregistered. To send a SPFILENOTIFY_STARTREGISTRATION or SPFILENOTIFY_ENDREGISTRATION notification to the callback routine, include SPINST_REGISTERCALLBACKAWARE plus either SPINST_REGSVR or SPINST_UNREGSVR. The caller must also set the MsgHandler parameter.
SPINST_REGSVR
To send a notification to the callback routine when registering a file, include SPINST_REGISTERCALLBACKAWARE plus SPINST_REGSVR in Flags. The caller must also specify the MsgHandler parameter.
SPINST_UNREGSVR
To send a notification to the callback routine when unregistering a file, include SPINST_REGISTERCALLBACKAWARE plus SPINST_UNREGSVR in the Flags. The caller must also specify the MsgHandler parameter.
RelativeKeyRoot
Optional parameter that must be specified if Flags includes SPINST_REGISTRY or SPINST_INI2REG. Handle to a registry key to be used as the root when the INF file specifies HKR as the key. Note that this parameter is ignored if SetupInstallFromInfSection is called with the optional DeviceInfoSet and DeviceInfoData set.
SourceRootPath
Source root for file copies. An example would be A:\ or \pegasus\win\install. If Flags includes SPINST_FILES, and SourceRootPath is NULL, the system provides a default root path.
CopyFlags
Optional parameter that must be specified if Flags includes SPINST_FILES. Specifies flags to be passed to the SetupQueueCopySection function when files are queued for copy. 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_OR_SAME
Examine each file being copied to see if its version resources indicate that it is either the same version or 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_FIXEDFILEINFO structure, as filled in by the 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 equal in version or 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_NEWER_ONLY
Examine each file being copied to see if its version resources indicate that it is not newer than an existing copy on the target. If the source file is newer but not equal in version to the existing target, the file is 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:/x86\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, no language or version information can be checked.
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 inform the user that the system needs to be rebooted. This flag is only used when later calling SetupPromptReboot or SetupScanFileQueue.
SP_COPY_NOSKIP
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 time stamps 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.)
MsgHandler
Pointer to the callback routine. The callback routine must be in the format of FileCallback. See Notifications for more information.
This parameter is optional only if the Flags parameter does not include SPINST_FILES, SPINST_REGISTERCALLBACKAWARE plus SPINST_REGSVR, or SPINST_UNREGSVR.
MsgHandler must be set if Flags includes SPINST_FILES. In this case, notification is sent to the callback routine when the file queue is committed with SetupCommitFileQueue.
MsgHandler must be set if Flags includes SPINST_REGISTERCALLBACKAWARE plus SPINST_REGSVR or SPINST_UNREGSVR. In this case a SPFILENOTIFY_STARTREGISTRATION or SPFILENOTIFY_ENDREGISTRATION is sent to the callback routine once each time a file is registered or unregistered using the RegisterDlls INF directive on Windows 2000.
Context
Value to be passed to the callback function when the file queue built by this routine internally is committed via SetupCommitFileQueue. The Context parameter is optional only if the Flags parameter does not include SPINST_FILES. This parameter must be specified if Flags includes SPINST_FILES.
DeviceInfoSet
Optional pointer to a handle to a device information set. For more information about the Device Installer setup functions, see the DDK Programmer's Guide.
DeviceInfoData
Optional pointer to a pointer to the SP_DEVINFO_DATA structure that provides a context to a specific element in the set specified by DeviceInfoSet. For more information about the Device Installer setup functions, see the DDK Programmer's Guide.
Return value
If the function succeeds, the return value is a nonzero value.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
Remarks
If a UNC directory is specified as the target directory of a file copy operation, you must ensure it exists before you call SetupInstallFromInfSection. 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.
This function requires a Windows INF file. Some older INF file formats may not be supported.
Note
The setupapi.h header defines SetupInstallFromInfSection as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
