*
* SCARDCONTEXT
*
* The context is a communication channel with the smart card resource manager and
* all calls to the resource manager must go through this link.
*
* All functions that take a context as a parameter or a card handle as parameter,
* which is indirectly associated with a particular context, may be blocking calls.
* Examples of these are SCardGetStatusChange and SCardBeginTransaction, which takes
* a card handle as a parameter. 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.
