SetupInstallFileEx function

[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 SetupInstallFileEx function installs a file as specified either by an INFCONTEXT returned by SetupFindXXXLine or explicitly by the filename and path information. This function is the same as SetupInstallFile, except that a BOOL is returned that indicates whether the file was in use.

If a file is copied, the caller of this function is required to have privileges to write into the target directory.

Syntax


BOOL SetupInstallFileEx(
  _In_   HINF InfHandle,
  _In_   PINFCONTEXT InfContext,
  _In_   PCTSTR SourceFile,
  _In_   PCTSTR SourcePathRoot,
  _In_   PCTSTR DestinationName,
  _In_   DWORD CopyStyle,
  _In_   PSP_FILE_CALLBACK CopyMsgHandler,
  _In_   PVOID Context,
  _Out_  PBOOL FileWasInUse
);

Parameters

InfHandle [in]

Optional pointer to the handle to an INF file that contains the SourceDisksNames and SourceDisksFiles sections. If platform-specific sections exist for the user's system (for example, SourceDisksNames.x86 and SourceDisksFiles.x86), the platform-specific section are used. If InfContext is not specified and CopyStyle includes SP_COPY_SOURCE_ABSOLUTE or SP_COPY_SOURCEPATH_ABSOLUTE, InfHandle is ignored.

InfContext [in]

Optional pointer to context for a line in a Copy Files section in an INF file. The routine looks this file up in the SourceDisksFiles section of InfHandle to get file copy information. If InfContext is not specified, SourceFile must be.

SourceFile [in]

Optional pointer to the filename (no path) of the file to copy. The file is looked up in the SourceDisksFiles section. The SourceFile parameter must be specified if InfContext is not. However, SourceFile is ignored if InfContext is specified.

SourcePathRoot [in]

Optional pointer to the root path for the file to be copied (for example, A:\ or F:\). Paths in the SourceDisksNames section are appended to this path. The SourcePathRoot parameter is ignored if CopyStyle includes the SP_COPY_SOURCE_ABSOLUTE flag.

DestinationName [in]

Optional pointer to a new name for the copied file. If InfContext is specified, DestinationName supplies the filename only (no path) of the target file. This parameter can be NULL to indicate that the target file should have the same name as the source file. If InfContext is not specified, DestinationName supplies the full target path and filename for the target.

CopyStyle [in]

Flags that control the behavior of the file copy operation.

These flags can be a combination of the following values.

ValueMeaning
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 overwrites 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 newer or equal in version, 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, alert the user that the system requires a reboot.

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.)

 

CopyMsgHandler [in]

Optional pointer to a callback function to be notified of various conditions that may arise during the file copy.

Context [in]

Pointer to a caller-defined value that is passed as the first parameter of the callback function.

FileWasInUse [out]

Pointer to a variable in which this function returns a flag that indicates whether the file was in use. This parameter is required.

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.

If GetLastError returns NO_ERROR, the file copy operation was not completed. The file may not have been copied because the file copy operation was unnecessary or because the file callback function returned FALSE.

Remarks

This API is typically used when installing new versions of system files that are likely to be in use. It updates a BOOL value that indicates whether the file was in use. If the file was in use, then the file copy operation is postponed until the system is rebooted.

If a UNC directory is specified as the target directory of a file installation, you must ensure it exists before you call SetupInstallFileEx. 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 fails.
