If such a function blocks then all operations wanting * to use the context are blocked as well. So, it is recommended that a CSP using * monitoring establishes at least two contexts with the resource manager; one for * monitoring (with SCardGetStatusChange) and one for other operations. * * If multiple cards are present, it is recommended that a separate context or pair * of contexts be established for each card to prevent operations on one card from * blocking operations on another. * * Example one * * The example below shows what can happen if a CSP using SCardGetStatusChange for * monitoring does not establish two contexts with the resource manager. * The context becomes unusable until SCardGetStatusChange unblocks. * * In this example, there is one process running called P1. * P1 calls SCardEstablishContext, which returns the context hCtx. * P1 calls SCardConnect (with the hCtx context) which returns a handle to the card, hCard. * P1 calls SCardGetStatusChange (with the hCtx context) which blocks because * there are no status changes to report. * Until the thread running SCardGetStatusChange unblocks, another thread in P1 trying to * perform an operation using the context hCtx (or the card hCard) will also be blocked. * * Example two * * The example below shows how transaction control ensures that operations meant to be * performed without interruption can do so safely within a transaction. * * In this example, there are two different processes running; P1 and P2. * P1 calls SCardEstablishContext, which returns the context hCtx1. * P2 calls SCardEstablishContext, which returns the context hCtx2. * P1 calls SCardConnect (with the hCtx1 context) which returns a handle to the card, hCard1. * P2 calls SCardConnect (with the hCtx2 context) which returns a handle to the same card, hCard2. * P1 calls SCardBeginTransaction (with the hCard 1 context). * Until P1 calls SCardEndTransaction (with the hCard1 context), * any operation using hCard2 will be blocked. * Once an operation using hCard2 is blocked and until it's returning, * any operation using hCtx2 (and hCard2) will also be blocked. */ //#define DISABLE_PCSC_SCARD_AUTOALLOCATE struct _PCSC_SCARDCONTEXT { CRITICAL_SECTION lock; SCARDCONTEXT hContext; DWORD dwCardHandleCount; BOOL isTransactionLocked; }; typedef struct _PCSC_SCARDCONTEXT PCSC_SCARDCONTEXT; struct _PCSC_SCARDHANDLE { CRITICAL_SECTION lock; SCARDCONTEXT hSharedContext; SCARDCONTEXT hPrivateContext; }; typedef struct _PCSC_SCARDHANDLE PCSC_SCARDHANDLE; struct _PCSC_READER { char* namePCSC; char* nameWinSCard; }; typedef struct _PCSC_READER PCSC_READER; static HMODULE g_PCSCModule = NULL; static PCSCFunctionTable g_PCSC = { 0 }; static HANDLE g_StartedEvent = NULL; static int g_StartedEventRefCount = 0; static BOOL g_SCardAutoAllocate = FALSE; static BOOL g_PnP_Notification = TRUE; #ifdef __MACOSX__ static unsigned int OSXVersion = 0; #endif /** * g_LockTransactions: enable pcsc-lite SCardBeginTransaction/SCardEndTransaction. * * After wasting months trying to fix and work around an appalling number of serious issues * in both the pcsc-lite client library and the pcscd daemon, I decided to just give up on * the transaction system.
