Win32API::File v0.07 -- Low-level access to Win32 API calls for files.

Low-level and full-power access to the following routines are provided:

	CloseHandle		CopyFile		CreateFile
	DefineDosDevice		DeleteFile		DeviceIoControl
	GetDriveType		GetFileType		GetLogicalDrives
	GetLogicalDriveStrings	GetVolumeInformation	IsRecognizedPartition
	IsContainerPartition	MoveFile		MoveFileEx
	QueryDosDevice		ReadFile		SetFilePointer
	SetErrorMode		WriteFile

Plus the Unicode versions:

	CopyFileW		CreateFileW		DefineDosDeviceW
	DeleteFileW		GetDriveTypeW		GetLogicalDriveStringsW
	GetVolumeInformationW	MoveFileW		MoveFileExW
	QueryDosDeviceW

Full conversion between Win32-native file handles and Perl file handles is
also supported.  Access to the following C run-time library routines [or at
least the Perl run-time library wrappers for them] is provided:

	_get_osfhandle or win32_get_osfhandle	as FdGetOsFHandle		
	_open_osfhandle or win32_open_osfhandle	as OsFHandleOpenFd
