Installers can use the device installation functions provided by Setup to carry out installation operations. The device installation functions allow installers to search INF files for compatible drivers, display driver choices to the user through selection dialogs, and perform the actual driver installation.
Most of the device installation functions rely on information in the SP_DEVINFO_DATA structure to carry out installation tasks. Each device has an SP_DEVINFO_DATA structure associated with it. You can retrieve a handle (HDEVINFO) to a device information set that contains all installed devices in a particular class by using the SetupDiGetClassDevs function. You can use the SetupDiCreateDeviceInfo function to add a new device to a device information set. You can free all SP_DEVINFO_DATA structures in a device information set by using the SetupDiDestroyDeviceInfoList function. This function also frees any compatible device and class device lists that may have been added to the structure.
By using the SetupDiBuildDriverInfoList function, you can generate a list of selections from which the installer or the user can choose the driver or device to install. SetupDiBuildDriverInfoList creates a list of compatible drivers or a list of all devices of a particular class.
Once you have a list of compatible drivers, you can prompt the user to select from the list by using the SetupDiSelectDevice function. This function displays a dialog box that contains information about each device in the device information set. You can install a selected driver by using the SetupDiInstallDevice function. This function uses information in the driver’s INF file to create to any new registry entries required, set the configuration of the device hardware, and copy the driver files to the appropriate directories.
An installer might need to examine and set values under the registry key for a device that is about to be installed. You can open the hardware or driver key for a device by using the SetupDiCreateDevRegKey or SetupDiOpenDevRegKey function.
You can install a new class of device by using the SetupDiInstallClass function. This function installs the new class of device from an INF file that contains a ClassInstall32 section.
You can remove a device from the system by using the SetupDiRemoveDevice function. This function deletes the device’s registry entries and stops the device if possible. If the device cannot be dynamically stopped, the function sets flags that eventually cause the user to be prompted to shut down the system.
Some device installation functions are intended to be used by the system and may not be useful for ordinary installers. You can call the installer for a particular class by using the SetupDiCallClassInstaller function. This function is useful if a device installer needs support from the corresponding class installer to complete installation. The function uses the class GUID in the HDEVINFO handle or SP_DEVINFO_DATA structure to locate, load, and call the appropriate class installer.
The device installation functions are briefly summarized below. See Device Installation Functions Reference for a detailed description of the these functions.
