VMMCall Get_Instanced_V86_Int_Vector

mov dword ptr [Handler], eax

Retrieves the address of the routine that handles the specified interrupt from a V86 interrupt table.

• Returns the address of the routine that handles the specified interrupt in the EAX register if successful; otherwise returns 0 in EAX. The high word of the EAX register contains the segment address of the interrupt-handling routine, and the low word of the EAX register contains the offset.

InterruptNumber

The interrupt number that causes the interrupt routine to be called.

VMHandle

VM handle.

The interrupt table is instanced per VM. For performance reasons, this service retrieves the address of the interrupt-handling routine without causing an instance fault. This service is preferred over accessing the interrupt vector table directly.
