[Pcsclite-muscle] SCARD_E_NOT_TRANSACTED

[Christophe FERRANDO]

Hi,

 

Same behaviour.

Please find the source code and the log file.

 

Source Code :

#include <stdio.h>

#include <stdlib.h>

#include <errno.h>

#include <string.h>

#include <time.h>

#include <sys/time.h>

#include <PCSC/winscard.h>

#include <PCSC/reader.h>

#include <wintypes.h>

 

 

#define CHECK(f, rv) \

if (SCARD_S_SUCCESS != rv) \

{ \

  printf(f ":[%lx] %s\n", rv, pcsc_stringify_error(rv)); \

  return -1; \

}

 

int main(int argc,char * argv[] )

{

LONG rv;

SCARDCONTEXT hContext;

LPTSTR mszReaders;

SCARDHANDLE hCard;

DWORD dwReaders, dwActiveProtocol, dwRecvLength;

unsigned char *pbAttr;

DWORD dwAttrLen;

DWORD dwState, dwProtocol, dwAtrLen, dwReaderLen;

BYTE *pbAtr = NULL;

char *pcReader = NULL;

SCARD_READERSTATE rgReaderStates[2];

 

rv = SCardEstablishContext(SCARD_SCOPE_USER, NULL, NULL, &hContext);

CHECK("SCardEstablishContext", rv)

rv = SCardConnect(hContext,"Microchip SEC1110 [CCID Interface] (72DE091F) 00 00",

            SCARD_SHARE_EXCLUSIVE,SCARD_PROTOCOL_T0, &hCard, &dwActiveProtocol);

CHECK("SCardConnect", rv);

rv = SCardEndTransaction(hCard,SCARD_LEAVE_CARD);

CHECK("SCardEndTransaction", rv);

rv = SCardDisconnect(hCard, SCARD_LEAVE_CARD);

CHECK("SCardDisconnect", rv)

rv = SCardReleaseContext(hContext);

CHECK("SCardReleaseContext", rv);

return 0;

}

 

 

 

Sincerly,

Christophe

Hi,

 

Hello,
 

 

I currently use pcsc-lite version 1.8.15.

 

If i use these instructions (C Program)

 

               rv = SCardEstablishContext(SCARD_SCOPE_USER, NULL, NULL, &hContext);

               CHECK("SCardEstablishContext", rv)

               rv = SCardConnect(hContext,"My Drive",

                         SCARD_SHARE_EXCLUSIVE,SCARD_PROTOCOL_T0, &hCard, &dwActiveProtocol);

               CHECK("SCardConnect", rv);

               rv = SCardEndTransaction(hCard,SCARD_LEAVE_CARD);

               CHECK("SCardEndTransaction", rv);

               rv = SCardDisconnect(hCard, SCARD_LEAVE_CARD);

               CHECK("SCardDisconnect", rv)

               rv = SCardReleaseContext(hContext);

               CHECK("SCardReleaseContext", rv)

 

I have no errors.

 

I expected SCARD_E_NOT_TRANSACTED because i call ScardEndTransaction without a previous call to ScardBeginTransaction.

But the result of SCardEndTransaction is E_SUCCESS.

 

That is strange.
On my side I get the expected behavior:
SCardEndTransaction: Transaction failed. 0x80100016
 

Can you share your complete source code?


Can you also generate a pcscd trace as documented in http://pcsclite.alioth.debian.org/pcsclite.html#support

Thanks
