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.
