Routine Description:
Actual implementation of SetupInstallFileEx. Handles either ANSI or Unicode callback routine.
Arguments:
Same as SetupInstallFileEx().
QueueNode - must be specified if Queue is supplied. This parameter gives us the queue node for this operation so we can get at the pertinent catalog info for driver signing.
IsMsgHandlerNativeCharWidth - supplies a flag indicating whether CopyMsgHandler expects native char widths args (or ansi ones, in the unicode build of the dll).
SignatureVerifyFailed - supplies the address of a boolean variable that is set to indicate whether or not digital signature verification failed for the source file. This will be set to FALSE if some other failure caused us to abort prior to attempting the signature verification. This is used by the queue commit routines to determine whether or not the queue callback routine should be given a chance to handle a copy failure (skip, retry, etc.). Digital signature verification failures are handled within this routine (including user prompting, if policy requires it), and queue callback routines _are not_ allowed to override the behavior.
Return Value:
Same as SetupInstallFileEx().

Routine Description:
Note: no disk prompting is performed by this routine. The caller must ensure that the source specified in SourcePathRoot or SourceFile (see below) is accessible.
Arguments:
InfHandle - handle of inf file containing [SourceDisksNames] and [SourceDisksFiles] sections. If InfContext is not specified and CopyFlags includes SP_COPY_SOURCE_ABSOLUTE or SP_COPY_SOURCEPATH_ABSOLUTE, then InfHandle is ignored.
InfContext - if specified, supplies context for a line in a copy file section in an inf file. The routine looks this file up in the [SourceDisksFiles] section of InfHandle to get file copy info. If not specified, SourceFile must be. If this parameter is specified, then InfHandle must also be specified.
SourceFile - if specified, supplies the file name (no path) of the file to be copied. The file is looked up in [SourceDisksFiles]. Must be specified if InfContext is not; ignored if InfContext is specified.
SourcePathRoot - Supplies the root path for the source (for example, a:\ or f:\). Paths in [SourceDisksNames] are appended to this path. Ignored if CopyStyle includes SP_COPY_SOURCE_ABSOLUTE.
DestinationName - if InfContext is specified, supplies the filename only (no path) of the target file. Can be NULL to indicate that the target file is to have the same name as the source file. If InfContext is not specified, supplies the full target path and filename for the target file.
CopyStyle - supplies flags that control the behavior of the copy operation.
SP_COPY_DELETESOURCE - Delete the source file upon successful copy. The caller receives no notification 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 (or timestamps for non-image files) indicate that it it is not newer than an existing copy on the target. If so, and a CopyMsgHandler is specified, the caller is notified and may veto 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 no CopyMsgHandler is specified, the file is not overwritten.
SP_COPY_NODECOMP - Do not decompress the file. When this option is given, the target file is not given the uncompressed form of the source name (if appropriate). For example, copying f:\mips\cmd.ex_ to \\foo\bar will result a target file \\foo\bar\cmd.ex_. (If this flag wasn't specified the file would be decompressed and the target would be called \\foo\bar\cmd.exe). The filename part of the target file name is stripped and replaced with the filename of the soruce. When this option is given, SP_COPY_LANGUAGEAWARE and SP_COPY_NEWER are ignored.
SP_COPY_ALREADYDECOMP - assume file to be decompressed but may have compressed source name. In this case, rename the file on copy and check SP_COPY_LANGUAGEAWARE/SP_COPY_NEWER, but don't attempt to decompress the file any further.
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 a CopyMsgHandler is specified, the caller is notified and may veto the copy. If CopyMsgHandler is not specified, the file is not copied.
SP_COPY_SOURCE_ABSOLUTE - SourceFile is a full source path. Do not attempt to look it up in [SourceDisksNames].
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. 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 copy on next reboot.
CopyMsgHandler - if specified, supplies a callback function to be notified of various conditions that may arise during the file copy.
Context - supplies a caller-defined value to be passed as the first parameter to CopyMsgHandler.
Return Value:
TRUE if a file was copied. FALSE if not. Use GetLastError for extended error information. If GetLastError returns NO_ERROR, then the file copy was aborted because (a) it wasn't needed or (b) a callback function returned FALSE.
