IFDHCreateChannelByName(3SMARTCARD)			    Smartcard Library Functions 		       IFDHCreateChannelByName(3SMARTCARD)

NAME

       IFDHCreateChannelByName - create a communication channel with an IFD

SYNOPSIS

       #include <smartcard/ifdhandler.h>

       RESPONSECODE IFDHCreateChannelByName(DWORD Lun, LPSTR devicename);

PARAMETERS

       The IFDHCreateChannelByName() function takes the following parameters:

   Input
       Lun	       Logical Unit Number

       devicename      Device name path

DESCRIPTION

       The  IFDHCreateChannelByName()  function  opens a communication channel with a card terminal specified by devicename. This function can use
       open(2) or other system call to open the device and establish a communication path. The caller of  this	function  (smart  card	framework)
       assigns	a  logical unit number Lun per card terminal and slot and passes this value to IFDHCreateChannelByName().  If the IFD handler sup-
       ports multiple terminals with one instance of the handler (as indicated by capability TAG_IFD_SIMULTANEOUS_ACCESS),  it	communicates  with
       the card terminal corresponding to this Lun.

       If the IFD handler supports only one terminal with one slot per instance, it can choose to ignore the Lun.

       The Logical Unit Number, Lun is encoded as  0xXXXXYYYY, where

       YYYY	represents  the  lower 16 bits that correspond to the slot number for terminals with multiple slots. Most of the readers have only
		one slot, in which case YYYY is 0.

       XXXX	represents the next 16 bits that correspond to the card terminal and can range between 0 and a number returned by TAG_IFD_SUMULTA-
		NEOUS_ACCESS.

RETURN VALUES

       The following values are returned:

       IFD_SUCCESS		       Successful completion.

       IFD_COMMUNICATION_ERROR	       An error occurred.
