Low Level File Access

[cman]

I think I might have asked before ( but since forgotten  :red ) , how can low level file access be done in assembler? Can this be done as with an array ( set a pointer to the begining addess do the file structure and move back and forth by adding / subtracting offsets ). How is a Windows file stored in memory. Thanks!

If you mean creating a function to read the harddisk and then read the FAT structure it is difficult. But for only opening a file, you can use WriteFile function on the windows API.

A driver sys is needed,download a ddk (ddk98) to have some samples.

Unless you are interested in the ring0 driver level, it sounds like normal API style file IO. Have a look at the file IO macros in the MASM32 macro file as they use the normal API calls and this will almost exclusively do all of what you want.
