-->Required routines
The following routines are required by a WDM reader driver.
DriverEntry
Microsoft Smart Card Reader Driver
Initializes the driver object and the dispatch table.
AddDevice
Creates a device object for the smart card reader. In addition, AddDevice can call any of the following driver library routines:
- SmartcardInitialize (WDM) to complete driver initialization. Calling this routine in AddDevice is obligatory.
- SmartcardLogError (WDM) to log an error. Drivers must call this routine in AddDevice if SmartcardInitialize (WDM) fails.
- SmartcardCreateLink (WDM) to create a symbolic link for the reader device in the registry.
Unload
Removes the driver from the system.
DispatchCreate
-and-
Microsoft Card Reader Driver Update
DispatchClose
Supports IRP_MJ_CREATE and IRP_MJ_CLOSE<, respectively. To establish a connection to the reader, the resource manager sends IRP_MJ_CREATE to the reader driver. To sever the connection, the resource manager sends IRP_MJ_CLOSE.
DispatchCleanup
Supports IRP_MJ_CLEANUP, which the resource manager sends to the reader driver to cancel pending I/O requests.
DispatchPnP
Supports IRP_MJ_PNP
DispatchPower
Supports IRP_MJ_POWER.
DispatchDeviceControl
Supports IRP_MJ_DEVICE_CONTROL and is the main entry point for smart card requests. Upon receiving IRP_MJ_DEVICE_CONTROL, DispatchDeviceControl must immediately call SmartcardDeviceControl (WDM), which is the smart card driver library routine that handles device-control requests. The following code example shows how to call this library routine from a WDM driver:
If it is unable to handle the particular IOCTL that is indicated in the call, SmartcardDeviceControl will call the driver's callback for unknown IOCTL requests.
