VMMcall Simulate_Far_Call
 
The Simulate_Far_Call service simulates a far call to a procedure in the the
current virtual machine. This service sets the Client_CS and Client_IP
registers to the specified procedure address after saving the original
Client_CS and Client_IP registers on the stack of the current virtual
machine. When the virtual machine resumes execution (such as when the
Resume_Exec service is called), the system executes the specified procedure
and returns only when the procedure executes a far ret instruction.
