I'm surprised that nobody's mentioned the appropriate mkisofs commands
yet. "mkisofs -r -J -b floppyimage.raw -c boot.cat -o output.iso
/path/to/files" will write an ISO9660 file called "output.iso"
containing floppyimage.raw as the -boot floppy and boot.cat as the
-catalog, with /path/to/files on the ISO as well. You can burn this ISO
file to a CD-R blank with whatever you want. Note that floppyimage.raw
must be 1.44 or 2.88M in size; if you have the 1.7M Tom's RootBoot
image, you need to get the 2.88M one instead.
I believe that some CD-burning programs for 'Doze have the -b and -c
options, but they call them different things. Consult your manual for
Acraptek Sleazy CD Cremator or whatever; it'll probably be under the
keyword "bootable".

I think this snake in the grass is barking up the wrong tree. The OP
doesn't need to fiddle with raw devices to burn a bootable CD. But:
HANDLE tapehandle;
tapehandle=CreateFile("\\\\.\\Tape0", GENERIC_READ | GENERIC_WRITE,
0, 0, OPEN_EXISTING, NULL);
if(tapehandle == INVALID_HANDLE_VALUE)
barf();
/* various tape-specific things like PrepareTape() are used instead of
* ioctl() here. ReadFile() and WriteFile() get used on the handle.

See above. The functions used for *tapes* are documented, but sort-of
hidden in MSDN. The functions used for *disks* may not be. Finding the
device names can be the hard part; you can't "DIR \\.\" or anything.
ISTR that opendir()ing \\.\ and trying to readdir() it didn't work
either. *Sigh*, half-assed /dev implementations make Baby Cthulhu
cry....
