fileops.c
|

|
|
Abstract:
|
|
|
|
This file implements routines that manage the operations on files. Callers
|
|
can set and remove operations on any path. The operations can have optional
|
|
properties. The operation combinations and the number of properties are
|
|
well-defined, so that potential collisions can be found during testing.

|
after NT is installed.

|
|
FinalDest - Specifies the final destination for FileSpec. If NULL, file
|
|
is moved to a temporary location but is not copied to a final
|
|
location in GUI mode.
|
|
|
|
TempSpec - Specifies the temp dir or file to relocate the file to. The temp dir
|
|
must be on the same drive as SrcFileSpec.
|
|
|
|
TempSpecIsFile - Specifies TRUE if the prev param is a file
|

|
TempFileIn - If non-NULL, specifies the temporary file to use instead of

automatically generated name. Provided only for

TempFileOut - If non-NULL, receives the path to the temporary file location.

Routine Description:

WriteBackupFiles outputs the files needed by the text mode backup engine

|
|
|
backup.txt - Lists all files that need to be backed up, either
|
|
because they are Win9x-specific, or are replaced
|
|
during the upgrade.
|
|
|
|
moved.txt - Lists all files that were moved from a Win9x location

to a temporary or NT location
|
|
|
|
delfiles.txt - Lists all files that are new to the upgraded OS
|
|
|
|
deldirs.txt - Lists subdirectories that are new to the upgraded OS
|
|
|
|
Arguments:
|
|
|
|
Win9xSide - Specifies TRUE if setup is running on Win9x. This causes the
|
|
files to be generated for the rollback of an incomplete setup.
|
|
|
|
Specifies FALSE if setup is running on NT. This causes the
|
|
files to be generated for the rollback of the final NT OS.
|
|
|
|
TempDir - Specifies the setup temporary directory (%windir%\setup).
|
|
|
|
OutAmountOfSpaceIfCompressed - return amount of space for backup files, if
|
|
compression will apply.
|
|
|
|
OutAmountOfSpace - return amount of space for backup files, if compression
|
|
will not apply.
|
|
|
|
CompressionFactor - receives the compression factor in 0..100 range.
|
|
|
|
BootCabImagePadding - receives the backup disk space padding for
|
|
additional files.
|
|
|

TRUE if the files were created successfully, FALSE otherwise.
