SourceInfFileName
[in] Full path to the source INF file. You should use a null-terminated string. This path should not exceed MAX_PATH in size, including the terminating NULL.
OEMSourceMediaLocation
[in] Source location information to be stored in the precompiled INF (.pnf). This location information is specific to the source media type specified. You should use a null-terminated string. This path should not exceed MAX_PATH in size, including the terminating NULL.
OEMSourceMediaType
[in] Source media type referenced by the location information. This parameter may be one of the following values.
Value Meaning
SPOST_NONE No source media information is stored in the PNF file. The value of OEMSourceMediaLocation is ignored in this case.
SPOST_PATH OEMSourceMediaLocation contains a path to the source media. For example, if the media is on a floppy, this path might be "A:\". If OEMSourceMediaLocation is NULL, the path is assumed to be the path where the INF is located. If the INF has a corresponding PNF in that location, the PNF file's source media information will be transferred to the destination PNF file.
SPOST_URL OEMSourceMediaLocation contains a universal resource locator (URL) specifying the Internet location from where the INF/driver files were retrieved. If OEMSourceMediaLocation is NULL, it is assumed that the default Code Download Manager location was used.
CopyStyle
[in] Specifies how the INF file is copied into the INF directory. The following flags can be combined.
Value Meaning
SP_COPY_DELETESOURCE Delete source file on successful copy.
SP_COPY_REPLACEONLY Copy only if this file already exists in the INF directory. This flag could be used to update the source location information for an existing INF.
SP_COPY_NOOVERWRITE Copy only if the specified files don't currently exist in the INF directory. If the INF does currently exist, this API will fail and GetLastError returns ERROR_FILE_EXISTS. In this case, the existing INF file's filename will be placed into the appropriate field in the destination INF file's information output buffers.
SP_COPY_OEMINF_CATALOG_ONLY The specified INF file's corresponding catalog files is copied to %windir%\Inf. If this flag is specified, the destination filename information is entered upon successful return if the specified INF file already exists in the Inf directory.
DestinationInfFileName
[out, optional] Pointer to a buffer to receive the INF file name assigned to it at the time it was copied to the INF directory. The buffer, if specified, should typically be MAX_PATH in length. If the SP_COPY_NOOVERWRITE flag is specified and the SetupCopyOEMInf function fails with a return code of ERROR_FILE_EXISTS, this buffer will contain the name of the existing INF file. If the SP_COPY_OEMINF_CATALOG_ONLY flag is specified, this buffer will contain the destination INF filename if the INF file is already present in the INF directory. Otherwise, this buffer will be set to the empty string. This parameter can be NULL.
DestinationInfFileNameSize
[in] Size of the DestinationInfFileName buffer, in characters, or zero if the buffer is not specified. If DestinationInfFileName is specified and this buffer size is less than the size required to return the destination INF filename (including full path), this function will fail. In this case GetLastError will return ERROR_INSUFFICIENT_BUFFER.
RequiredSize
[out, optional] Pointer to a variable that receives the size (in characters) required to store the destination INF file name including a terminating NULL. If the SP_COPY_OEMINF_CATALOG_ONLY flag is specified, this variable will receive a string length only if the INF file already exists in the INF directory. Otherwise, this variable will be set to zero. This parameter can be NULL.
DestinationInfFileNameComponent
[out, optional] Pointer to a string that is set upon successful return (or ERROR_FILE_EXISTS) to point to the beginning of the filename component of the path stored in the DestinationInfFileName parameter. If the SP_COPY_OEMINF_CATALOG_ONLY flag is specified, the DestinationInfFileName parameter may be an empty string. In this case, the character pointer will be set to NULL upon successful return. This parameter can be NULL.
Return Values
TRUE
The SetupCopyOEMInf function succeeded.
FALSE
The SetupCopyOEMInf function failed. For extended error information, call GetLastError.
Remarks
The SetupCopyOEMInf function copies a specified INF file into the %windir%\Inf directory. SetupCopyOEMInf does not recopy the file if it finds that a binary image of the specified INF file already exists in the INF directory with the same name or a name of the form OEM*.INF. When SetupCopyOEMInf copies a file, it renames the copied file to OEM*.INF. Name provided is unique and cannot be predicted.
SetupCopyOEMInf uses the following procedure to determine if the INF file already exists in the INF directory:
All INF files with names of the form OEM*.INF are enumerated and any files that have the same file size as the specified INF file are binary compared.
The INF directory is searched for the source filename of the INF file. If an INF file of the same name exists and is the same size as that of the specified INF file, the two files are binary compared to determine if they are identical.
If the specified INF file already exists a further check is performed to determine if the specified INF file contains a CatalogFile= entry in its [Version] section. If it does, the INF files's %windir%\Inf primary filename with a ".CAT" extension is used to determine if the catalog is already installed. If there is a catalog installed, but it isn't the same as the catalog associated with the source INF, this is not considered to be a match and enumerations continue. It is possible to have multiple identical INF files with unique catalogs contained in %windir%\Inf directory. If an existing match is not found, the INF and CAT files are installed under a new and unique name.
OEM INFs that don't specify a CatalogFile= entry are considered invalid with respect to digital signature verification.
In cases where the INF file must be copied to the %windir%\Inf directory, any digital signature verification failures are reported
If the INF and CAT files already exist, these existing filenames are used and the file replacement behavior is based on the specified CopyStyle flags. Replacement behavior refers only to the source media information stored in the PNF. Existing INF, PNF, and CAT files are not modified.
