Debug_Query

include vmm.inc

mov     eax, Debug_Query
VMMcall System_Control

Notifies a virtual device that the user has typed ".VxDNAME" in the debugger. (that is, a period followed by the name of the VxD.) This is a directed system control message. The virtual device typically responds to the message by displaying a menu of debugging services and reading command input from the user via In_Debug_Chr. The virtual device may use all general registers and flags.

• This message cannot be failed. The virtual device must return carry clear.

The handler for this message must not be in pageable memory. A Windows 95 VxD should placed the handler in the Debug_Only code segment.
