Hi,
do you mean the use of Winscard.lib or the use of
Smclib.lib ?
In our development platform when using Winscard.lib 2
different smart card readers connected to the platform
create two smart card devices - EZR1: and EZU1: by use of
one smart card reader driver, present in the system.
Then you can address each physical smart card reader by
accessing it by a number, like in
SCardEstablishContext() ...
SCardListReaders() call it twice, then do a loop
while((*readerName != '\0') && (ReadersNum <
MAX_READER_NUMBER))
{
ScardReaderState[ReadersNum].szReader = (LPTSTR)
readerName;
ScardReaderState
[ReadersNum].dwCurrentState=SCARD_STATE_UNAWARE;
++ReadersNum;
readerName += wcslen(readerName) + 1;
};
now you can work with chosen physical smart card reader
selecting it by number name in ScardReaderState array of
structures like in
result = SCardConnect(ScardContext,
ScardReaderState
[CurrentReader].szReader,
SCARD_SHARE_EXCLUSIVE,
SCARD_PROTOCOL_T0 |
SCARD_PROTOCOL_T1,
&ScardHandle[CurrentReader],
&ScardProtocol
[CurrentReader]);
where CurrentReader can 0 EZU1: for 1 for EZR1: .
Hope this helps.
Sincerely
Sergei
