Module win32file
An interface to the win32 File API's
This module includes the tranactional NTFS operations introduced with
Vista. The transacted functions are not wrapped separately, but are invoked by
passing a transaction handle to the corresponding Unicode API function.
This makes it simple to convert a set of file operations into a transaction by
simply adding Transaction=PyHANDLE to the passed arguments.
If Transaction is None, 0, or not specified, the non-transacted API function will
be called.
Functions combined in this manner:
CreateFile / CreateFileTransacted
DeleteFile / DeleteFileTransacted
CreateDirectoryEx / CreateDirectoryTransacted
MoveFileWithProgress / MoveFileTransacted
CopyFileEx / CopyFileTransacted
GetFileAttributes / GetFileAttributesTransacted
SetFileAttributes / SetFileAttributesTransacted
CreateHardLink / CreateHardLinkTransacted
CreateSymbolicLink / CreateSymbolicLinkTransacted
RemoveDirectory / RemoveDirectoryTransacted
