I wrote a utility long time ago using TC low level i/o routines.
For example, to revover an erased file, I need to read the directory entries
FAT, etc etc.  This is no problem using TC under DOS.  What I need to do is to
convert this utility to run under windows.  I have the Petzold book and it
does not list any low level file I/O or disk I/o routines, such as 
absread() and abswrite() which are available in TC.  

What I need to know is :

1.	Is it possible to do this without too much trouble.

2.	Are there any reference mannuals or books which lists all
	the functions that are available under windows.  I understand 
	there are about 450 functions that windows provide. I need to know
	thier usage in terms of syntax, return values, parameters, etc.etc.

I would appreciate if some one could provide me some details on this.


Thanks in advance.
