Int 2F/AX=120Fh

DOS 3.0+ internal - MAKE BUFFER MOST RECENTLY USED

AX = 120Fh
DS:DI -> disk buffer
SS = DOS DS (must be using a DOS internal stack)

Return:
DS:DI -> next buffer in buffer list

Desc: Move the indicated buffer to the end of the disk buffer chain (least- recently used is first); under DOS 3.3, the buffer is then moved to the start of the disk buffer chain if it was marked unused

Note: This function is the same as AX=1207h except that it returns a pointer to the buffer following the specified buffer in the buffer chain

See Also: AX=1207h
