Category: DOS kernel
Flags: callout or callback (usually hooked rather than called), Undocumented function
INT 2F - Novell DOS 7+ FDOS EXTENSIONS - READ BUFFERS
AX = 1002h
CH = FFh (pre-read required)
CL = buffer type (here FAT, DIR, or DATA, see below)
AH:DX = 24 bit sector number
Return: ES:SI -> buffer control block
Notes: This private function is called internally by the OS kernel to
ask the FDOS to find the corresponding buffer. By using the
INT 2F/AX=1001h FDOS hook, the call can be intercepted by external
system components such as the DELWATCH TSR.
This function must under no circumstances be called by applications!
