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 typedef struct _PCSC_SCARDCONTEXT PCSC_SCARDCONTEXT;
