Abstract:
|
|
|
|
Routines to manage installation of devices via the answer file.
|
|
|
|
The main entry points are:
|
|
|
|
CreateAfDriverTable
|
|
DestroyAfDriverTable
|
|
SyssetupInstallAnswerFileDriver
|
|
CountAfDrivers
|
|
|
|
The rest of the functions are utilities or routines used by outside
|
|
callers only in a special case of some sort.

Routine Description:
|
|
|
|
SyssetupFixAnswerFileDriverPath calls SetupCopyOEMFile to copy the device
|
|
INF over itself. The source is the same as the destination, which causes
|
|
the PNF to be rebuilt, and doesn't cause any copy
|
|
activity.
|
|
|
|
|
|
Arguments:
|
|
|
|
Driver - Specifies the attributes of the answer file-supplied driver
|
|
hDevInfo - Specifies the device. The driver for this device must
|
|
already be installed.
|
|
DeviceInfoData - Specifies the device info
|
|
|
|
Return Value:
|
|
|
|
TRUE if the PNF was updated, FALSE otherwise.
