SHELL_Update_User_Activity


include shell.inc
VxDcall SHELL_Update_User_Activity

Notifies the shell VxD that user input has occurred. This information is used to determine whether the user is actively using the system, which controls things such as the screen saver.

This is an asynchronous service.

This service is intened to be called by virtual devices that handle user input, such as the virtual mouse device (VMD) and virtual keyboard device (VKD). A graphics tablet driver, for example, can call this service when it detects activity on the tablet, so that the screen saver does not interrupt a user who is in the middle of using the tablet.
