2005-09-28 Corinna Vinschen <corinna@vinschen.de>
* fhandler.h (class fhandler_dev_raw): Delete current_position and
eof_detected status flag. Delete is_eom and is_eof methods.
Move drive_size, bytes_per_sector, eom_detected status flag, as well
as the methods read_file, write_file, raw_read and raw_write to ...
(class fhandler_dev_floppy): ... here. Remove is_eom and is_eof
methods. Add dup method.
* fhandler_floppy.cc (IS_EOM): New macro.
(fhandler_dev_floppy::is_eom): Remove.
(fhandler_dev_floppy::is_eof): Remove.
(fhandler_dev_floppy::fhandler_dev_floppy): Initialize status flags.
(fhandler_dev_floppy::get_drive_info): Only call EX functions on
systems supporting them and stop suffering strange delays.
(fhandler_dev_floppy::read_file): Move here, drop setting
current_position.
(fhandler_dev_floppy::write_file): Move here, drop setting
current_position.
(fhandler_dev_floppy::open): Rearrange comment.
(fhandler_dev_floppy::dup): New method.
(fhandler_dev_floppy::get_current_position): New inline method. Use
instead of former current_position were appropriate.
(fhandler_dev_floppy::raw_read): Move here. Drop EOF handling.
(fhandler_dev_floppy::raw_write): Move here. Drop EOF handling.
(fhandler_dev_floppy::lseek): Remove useless conditions. Convert
sector_aligned_offset to LARGE_INTEGER to improve SetFilePointer call.
(fhandler_dev_floppy::ioctl): Move blocksize check in RDSETBLK case
to here.
* fhandler_raw.cc (fhandler_dev_raw::is_eom): Remove.
(fhandler_dev_raw::is_eof): Remove.
(fhandler_dev_raw::write_file): Remove.
(fhandler_dev_raw::read_file): Remove.
(fhandler_dev_raw::raw_read): Remove.
(fhandler_dev_raw::raw_write): Remove.
(fhandler_dev_raw::dup): Drop copying removed members.
(fhandler_dev_raw::ioctl): Drop blocksize testing.
* wincap.h: Implement has_disk_ex_ioctls throughout.
* wincap.cc: Ditto.
(wincap_vista): Preliminary wincaps for Windows Vista/Longhorn.
(wincapc::init): Add Vista/Longhorn handling.
2005-09-28 Christopher Faylor <cgf@timesys.com>
* dcrt0.cc (getstack): New function.
