Routine Description:
|
|
|
|
The attributes of a file can be set using SetFileAttributes.
|
|
|
|
This API provides the same functionality as DOS (int 21h, function
|
|
43H with AL=1), and provides a subset of OS/2's DosSetFileInfo.
|
|
|
|
Arguments:
|
|
|
|
lpFileName - Supplies the file name of the file whose attributes are to
|
|
be set.
|
|
|
|
dwFileAttributes - Specifies the file attributes to be set for the
|
|
file. Any combination of flags is acceptable except that all
|
|
other flags override the normal file attribute,
|
|
FILE_ATTRIBUTE_NORMAL.
|
|
|
|
FileAttributes Flags:
|
|
|
|
FILE_ATTRIBUTE_NORMAL - A normal file should be created.
|
|
|
|
FILE_ATTRIBUTE_READONLY - A read-only file should be created.
|
|
|
|
FILE_ATTRIBUTE_HIDDEN - A hidden file should be created.
|
|
|
|
FILE_ATTRIBUTE_SYSTEM - A system file should be created.
|
|
|
|
FILE_ATTRIBUTE_ARCHIVE - The file should be marked so that it
|
|
will be archived.
|
|
|
|
Return Value:
|
|
|
|
TRUE - The operation was successful.
|
|
|
|
FALSE/NULL - The operation failed. Extended error status is available
|
|
using GetLastError.

Routine Description:
|
|
|
|
An existing file can be renamed using MoveFileWithProgressW.
|
|
|
|
Arguments:
|
|
|
|
lpExistingFileName - Supplies the name of an existing file that is to be
|
|
renamed.
|
|
|
|
lpNewFileName - Supplies the new name for the existing file. The new
|
|
name must reside in the same file system/drive as the existing
|
|
file and must not already exist.
|
|
|
|
lpProgressRoutine - Supplies a callback routine that is notified.
|
|
|
|
lpData - Supplies context data passed to the progress routine.
|
|
|
|
dwFlags - Supplies optional flag bits to control the behavior of the
|
|
rename. The following bits are currently defined:
|
|
|
|
MOVEFILE_REPLACE_EXISTING - if the new file name exists, replace
|
|
it by renaming the old file name on top of the new file name.
|
|
|
|
MOVEFILE_COPY_ALLOWED - if the new file name is on a different
|
|
volume than the old file name, and causes the rename operation
|
|
to fail, then setting this flag allows the MoveFileEx API
|
|
call to simulate the rename with a call to CopyFile followed
|
|
by a call to DeleteFile to the delete the old file if the
|
|
CopyFile was successful.
|
|
|
|
MOVEFILE_DELAY_UNTIL_REBOOT - dont actually do the rename now, but
|
|
instead queue the rename so that it will happen the next time
|
|
the system boots. If this flag is set, then the lpNewFileName
|
|
parameter may be NULL, in which case a delay DeleteFile of
|
|
the old file name will occur the next time the system is
|
|
booted.
|
|
|
|
The delay rename/delete operations occur immediately after
|
|
AUTOCHK is run, but prior to creating any paging files, so
|
|
it can be used to delete paging files from previous boots
|
|
before they are reused.
|
|
|
|
MOVEFILE_WRITE_THROUGH - perform the rename operation in such a
|
|
way that the file has actually been moved on the disk before
|
|
the API returns to the caller. Note that this flag causes a
|
|
flush at the end of a copy operation (if one were allowed and
|
|
necessary), and has no effect if the rename operation is
|
|
delayed until the next reboot.
|
|
|
|
MOVEFILE_CREATE_HARDLINK - create a hard link from the new file name to
|
|
the existing file name. May not be specified with
|
|
MOVEFILE_DELAY_UNTIL_REBOOT
|
|
|
|
MOVEFILE_FAIL_IF_NOT_TRACKABLE - fail the move request if the file cannot
|
|
be tracked.
|
|
|
|
Return Value:
|
|
|
|
TRUE - The operation was successful.
|
|
|
|
FALSE/NULL - The operation failed. Extended error status is available
|
|
using GetLastError.

Routine Description:
|
|
|
|
Moves an identity from one file to another. The identity is composed
|
|
of the file's create date, and its object ID. The Object ID isn't
|
|
necessarily copied straight across; it's handled as if the actual
|
|
file were being moved by MoveFileWithProgressW.
|
|
|
|
Arguments:
|
|
|
|
lpOldFileName - Supplies the old file name
|
|
|
|
lpNewFileName - Supplies the new file name
|
|
|
|
Return Value:
|
|
|
|
TRUE if successful. Otherwise the error can be found by calling GetLastError().
