Windows 98 Smartcard drivers must call the SmartcardCreateLink function (300600)


The information in this article applies to:

  • Microsoft Windows 98
  • Microsoft Windows 98 Driver Development Kit (DDK)
This article was previously published under Q300600

SYMPTOMS

On Microsoft Windows 98, a program may not successfully call the SCardConnect function. Therefore, communication with the Smartcard device cannot occur.

CAUSE

On Windows 98, the Smartcard Resource Manager can access only those devices that create a symbolic link.

RESOLUTION

Configure Smartcard drivers to call the SmartcardCreateLink to create a symbolic link so that the Smartcard Resource Manager can access the reader.

STATUS

This behavior is by design.

MORE INFORMATION

Although the Microsoft Windows 98 Driver Development Kit (DDK) Smartcard Windows Driver Model (WDM) driver sample uses the IoRegisterDeviceInterface function with the SmartCardReaderGuid function to register the reader and does not call the SmartcardCreateLink function, this method will not work on Windows 98, because the Windows 98 Resource Manager can only access devices that have symbolic links. On Windows 98, even WDM drivers must call SmartcardCreateLink.
