VMMcall Validate_Client_Ptr
 
The Validate_Client_Ptr service determines whether the address specified by
crs points to the Client_Reg_Struc structure for the current virtual
machine. If the address is not correct, the service crashes the current
virtual machine.
 
This is an asynchronous service.
 
Parameter  Description
────────────────────────────────────────────────────────────────────────────
 
crs        Points to the Client_Reg_Struc structure to check.
 
Return Value
 
This service has no return value.
 
Comments
 
This service never returns if the client register pointer is not valid.
 
If the current re-entry count for the VMM is not zero, this service returns
immediately without checking the client register pointer.
