Installable driver messages notify installable drivers of specific events, such as loading or unloading the driver, or direct the driver to carry out some action, such as displaying a configuration dialog box. The Microsoft Windows operating system, version 3.1, sends installable driver messages to the DriverProc function of an installable driver whenever an application calls functions, such as OpenDriver, SendDriverMessage, and CloseDriver.
This chapter lists the installable driver messages in alphabetic order.
