VPICD_Auto_Mask_At_Inst_Swap

include vpicd.inc

mov     eax, IRQHandle
VxDcall VPICD_Begin_Inst_Page_Swap
jc      errorhandler
 

Sets the state of an IRQ so that it is automatically masked when the virtual memory manager swaps data in an instance page. This allows a VxD to touch instance memory at interrupt time. This service can not be called at interrupt time. Uses Flags.

• Clears carry flag if successful.

IRQHandle

Handle of the IRQ.
