specifications of sys(\w+) functions
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!
