specifications of sys(\w+) functions Can't Post

Hey folks-

I am interested in the sys__ functions (sysopen, sysread, etc) and their implementation. How do, if at all, the sys__ functions cache the disk page?

>> say my page size is 40k and I want to read from a certain byte. does it buffer the 40k starting at that byte, ending at that byte, middling that byte, &c?

If anyone could give me any other information on how they work, I would appreciate it. thanks!

IMO it depends on specific platform implementation...

After all (AFAIK) the functions are only the interface to the OS's FS functions.
