Hello,

So I have been working on ifdhandler 3 which is basically ifdhandler 2
with some definitions of extended functionality for IFDHControl. It also
includes a callback function for instant status notification. pcscd will
look for these new symbols and use them only if they exist so there is no
rush to support these.

There are a couple of new tags:

       TAG_IFD_SLOTS_NUMBER - return the number of slots for this
                                     reader (default 1)
       TAG_IFD_SIMULTANEOUS_ACCESS - return the number of connected
                                     readers
                                     this driver can support
                                     simultaneously (default 1)

Here is the prototype for the callback function:

  typedef struct _SCARD_CALLBACK_INFO {
    DWORD logicalUnit; /* Lun of the event creating device */
    DWORD cardStatus; /* Status of the card */
    DWORD readerStatus; /* Status of the reader */
    DWORD extendStatus; /* Status of extended features ie: biometric */
    void *extendedData;
  } SCARD_CALLBACK_INFO, *PSCARD_CALLBACK_INFO;
 
  /* End of structure list */
 
 
/* Define for callback function */
typedef void (*LPCardEventCallback)(PSCARD_CALLBACK_INFO);

  RESPONSECODE IFDHRegisterCallback( LPCardEventCallback );

Suggestions ????

Dave
