IFDHPowerICC(3SMARTCARD)  Smartcard Library Functions IFDHPowerICC(3SMARTCARD)

NAME
       IFDHPowerICC - power up or power down the smart card

SYNOPSIS
       #include <smartcard/ifdhandler.h>

       RESPONSECODE  IFDHPowerICC(DWORD	 Lun, DWORD Action, PUCHAR Atr, PDWORD
       AtrLength);

PARAMETERS
       The IFDHPowerICC() takes the following parameters:

   Input
       Lun	       Logical Unit Number

       Action	       Action to be taken

       AtrLength       Maximum length of the ATR

   Output
       Atr	       Answer to Reset (ATR) value of the inserted card

       AtrLength       Actual length of the ATR

DESCRIPTION
       The IFDHPowerICC() function controls the power and reset signals of the
       ICC  (smart  card)  at the reader or slot specified by Lun.  The Action
       parameter can take one of the following values:

       IFD_POWER_UP	       Power and reset the card. Return	 the  ATR  and
			       its length.

       IFD_POWER_DOWN	       Power  down  the	 card.	The  Atr and AtrLength
			       parameters are set to 0.

       IFD_RESET	       Perform a quick reset on the card.  Return  the
			       ATR and its length.

       The  IFD	 handler caches the ATR during a power up or reset and returns
       the ATR and its length in a call to IFDHGetCapabilities(3SMARTCARD).

       Memory cards without an ATR return IFD_SUCCESS on power up or reset but
       Atr and AtrLength are set to 0.

RETURN VALUES
       The following values are returned:

       IFD_SUCCESS		       Successful completion.

       IFD_ERROR_POWER_ACTION	       An  error occurred while powering up or
				       resetting the card.

       IFD_NOT_SUPPORTED	       The action specified by Action  is  not
				       supported.

       IFD_COMMUNICATION_ERROR	       An error occurred.
