* NOTE: If RIS_HookTable is non-zero, then it is interpreted as a

|
* pointer to a Reclaim_Hook_Table, which provides a means
|
|
* for the system to automatically unhook a component in a reclaimable
|
|
* memory block from the rest of the system. It is also IMPORTANT to note
|
|
* that if a Reclaim_Hook_Table is specified, then the memory block will
|
|
* not be reclaimed UNLESS the RHT_DISABLED bit is also set. In other
|
|
* words, if the hooks associated with a block have not been disabled
|
|
* by the time the system attempts to reclaim the memory (Init_Complete),
|
|
* then the memory containing those hooks cannot be reclaimed.
|
|
*
|
|
* RHT_Num_Hooks is the number of hooks to be unhooked/rehooked at
|
|
* reclaim/restore time, RHT_Low_Seg is the segment of "stub code"
|
|
* that is always resident, RHT_High_Seg is the segment of "driver code"
|
|
* that is contained within (or identical to) RIS_Seg, and the entire
|
|
* Reclaim_Hook_Table is followed by an array of Reclaim_Hook_Entry
|
|
* structures, which contain pairs of offsets to dword vector addresses
|
|
* that must be exchanged in order to disable or re-enable the hooks.
|
|
* For each pair of offsets, the first is relative to RHT_Low_Seg and the
|
|
* second is relative to RHT_High_Seg. RHT_Num_Hooks is the number of
|
|
* Reclaim_Hook_Entry structures in the array.
|
|
*
|
|
* The system will only unhook all the hooks in a Reclaim_Hook_Table if
|
|
* RHT_DISABLED bit is set and RHT_UNHOOKED is NOT set in RHT_Flags (meaning
|
|
* that a Vxd or other component has assumed responsibility for the code
|
|
* inside the hooks and has not unhooked them itself).
|
|
*
|
|
* Since the Reclaim_Hook_Table must be inside the segment being reclaimed,
|
|
* it follows that unhooking will occur before memory reclamation, and that
|
|
* memory restoration will occur before re-hooking.
|
|
*
|
|
* VxDs are free to perform their own real-mode vector hooking/unhooking
|
|
* on their own. This mechanism is used by the DBLSPACE/DRVSPACE drivers,
|
|
* and is simply exported as a convenience for other drivers.
