VMMcall Disable_Local_Trapping

Disables I/O port trapping for the specified I/O port. This applies only to the specified virtual machine. Uses Flags.

• No return value.

VM

Handle of the virtual machine for which to disable I/O trapping.

Port

Number of the I/O port for which trapping is disabled.

This service must not be used unless an I/O callback procedure has been installed for the given port using the Install_IO_Handler or Install_Mult_IO_Handlers service during initialization. In particular, you should not attempt to alter the port trapping state of a port for which you did not personally install an I/O handler. Altering the port trapping state of a port owned by another virtual device driver may cause that other driver to get confused.
