Functions

static int CHANNEL_MAP_seeker (const void *el, const void *key)
static LONG getReaderStates (SCONTEXTMAP *currentContextMap)
static LONG SCardAddContext (SCARDCONTEXT hContext, DWORD dwClientID)
 Adds an Application Context to the vector _psContextMap.
static LONG SCardAddHandle (SCARDHANDLE, SCONTEXTMAP *, LPCSTR)
LONG SCardBeginTransaction (SCARDHANDLE hCard)
 This function establishes a temporary exclusive access mode for doing a serie of commands in a transaction.
LONG SCardCancel (SCARDCONTEXT hContext)
LONG SCardCancelTransaction (SCARDHANDLE hCard)
LONG SCardCheckDaemonAvailability (void)
 Checks if the server is running.
static LONG SCardCleanContext (SCONTEXTMAP *)
LONG SCardConnect (SCARDCONTEXT hContext, LPCSTR szReader, DWORD dwShareMode, DWORD dwPreferredProtocols, LPSCARDHANDLE phCard, LPDWORD pdwActiveProtocol)
 This function establishes a connection to the reader specified in szReader.
LONG SCardControl (SCARDHANDLE hCard, DWORD dwControlCode, LPCVOID pbSendBuffer, DWORD cbSendLength, LPVOID pbRecvBuffer, DWORD cbRecvLength, LPDWORD lpBytesReturned)
 This function sends a command directly to the IFD Handler (reader driver) to be processed by the reader.
LONG SCardDisconnect (SCARDHANDLE hCard, DWORD dwDisposition)
 This function terminates a connection made through SCardConnect().
LONG SCardEndTransaction (SCARDHANDLE hCard, DWORD dwDisposition)
 This function ends a previously begun transaction.
LONG SCardEstablishContext (DWORD dwScope, LPCVOID pvReserved1, LPCVOID pvReserved2, LPSCARDCONTEXT phContext)
 Creates an Application Context to the PC/SC Resource Manager.
static LONG SCardEstablishContextTH (DWORD dwScope,LPCVOID pvReserved1,LPCVOID pvReserved2, LPSCARDCONTEXT phContext)
 Creates a communication context to the PC/SC Resource Manager.
LONG SCardFreeMemory (SCARDCONTEXT hContext, LPCVOID pvMem)
 Releases memory that has been returned from the resource manager using the SCARD_AUTOALLOCATE length designator.
LONG SCardGetAttrib (SCARDHANDLE hCard, DWORD dwAttrId, LPBYTE pbAttr, LPDWORD pcbAttrLen)
 This function get an attribute from the IFD Handler (reader driver).
static SCONTEXTMAPSCardGetContext (SCARDCONTEXT hContext)
 Get the index from the Application Context vector _psContextMap for the passed context.
static LONG SCardGetContextAndChannelFromHandle (SCARDHANDLE, SCONTEXTMAP **, CHANNEL_MAP **)
static LONG SCardGetContextAndChannelFromHandleTH (SCARDHANDLE, SCONTEXTMAP **, CHANNEL_MAP **)
static SCONTEXTMAPSCardGetContextTH (SCARDCONTEXT hContext)
 Get the address from the Application Context list _psContextMap for the passed context.
static LONG SCardGetSetAttrib (SCARDHANDLE hCard, int command, DWORD dwAttrId, LPBYTE pbAttr, LPDWORD pcbAttrLen)
LONG SCardGetStatusChange (SCARDCONTEXT hContext, DWORD dwTimeout, LPSCARD_READERSTATE_A rgReaderStates, DWORD cReaders)
 This function blocks execution until the current availability of the cards in a specific set of readers changes.
static LONG SCardInvalidateHandles (void)
LONG SCardIsValidContext (SCARDCONTEXT hContext)
 Check if a SCARDCONTEXT is valid.
LONG SCardListReaderGroups (SCARDCONTEXT hContext, LPSTR mszGroups, LPDWORD pcchGroups)
 This function returns a list of currently available reader groups on the system. mszGroups is a pointer to a character string that is allocated by the application. If the application sends mszGroups as NULL then this function will return the size of the buffer needed to allocate in pcchGroups.
LONG SCardListReaders (SCARDCONTEXT hContext, LPCSTR mszGroups, LPSTR mszReaders, LPDWORD pcchReaders)
static LONG SCardLockThread (void)
 This function locks a mutex so another thread must wait to use this function.
LONG SCardReconnect (SCARDHANDLE hCard, DWORD dwShareMode, DWORD dwPreferredProtocols, DWORD dwInitialization, LPDWORD pdwActiveProtocol)
 This function reestablishes a connection to a reader that was previously connected to using SCardConnect().
LONG SCardReleaseContext (SCARDCONTEXT hContext)
 This function destroys a communication context to the PC/SC Resource Manager. This must be the last function called in a PC/SC application.
static LONG SCardRemoveContext (SCARDCONTEXT hContext)
 Removes an Application Context from a control vector.
static LONG SCardRemoveHandle (SCARDHANDLE)
LONG SCardSetAttrib (SCARDHANDLE hCard, DWORD dwAttrId, LPCBYTE pbAttr, DWORD cbAttrLen)
 This function set an attribute of the IFD Handler.
LONG SCardSetTimeout (SCARDCONTEXT hContext, DWORD dwTimeout)
 The function does not do anything except returning SCARD_S_SUCCESS.
LONG SCardStatus (SCARDHANDLE hCard, LPSTR mszReaderName, LPDWORD pcchReaderLen, LPDWORD pdwState, LPDWORD pdwProtocol, LPBYTE pbAtr, LPDWORD pcbAtrLen)
 This function returns the current status of the reader connected to by hCard.
LONG SCardTransmit (SCARDHANDLE hCard, LPCSCARD_IO_REQUEST pioSendPci, LPCBYTE pbSendBuffer, DWORD cbSendLength, LPSCARD_IO_REQUEST pioRecvPci, LPBYTE pbRecvBuffer, LPDWORD pcbRecvLength)
 This function sends an APDU to the smart card contained in the reader connected to by SCardConnect().
static LONG SCardUnlockThread (void)
 This function unlocks a mutex so another thread may use the client.
static int SCONTEXTMAP_seeker (const void *el, const void *key)
