Create_Thread

include vmm.inc

mov     edi, ThreadHandle
mov     eax, Create_Thread
VMMcall System_Control

Notifies a virtual device that the system is creating a new thread. Virtual devices typically create and initialize any structures needed to support the new thread. The virtual device may use all general registers and flags.

• The virtual device returns with carry clear to allow the thread to be created, or with carry set to prevent it from being created.

ThreadHandle

Handle of the thread being created. The thread being created is not the current thread.

If the virtual device sets the carry flag to prevent creation the thread, it should free any system resource it may have allocated to support the thread.

Interrupt simulation is not permitted in the new thread during this message.

Note that this mesage is not sent when a new virtual machine is created, even though each virtual machine also comes with a thread. Therefore, if you need to do something whenever a new thread is created, even if it is the thread of a virtual machine, you need to perform the operation on the VM_Create message as well.
