You might want to use this when you are selecting a few files and then writing a large file so you can make sure that another application will not change the current file. If another application has a lock on this reader or this application is in

This function receives a structure or list of structures containing reader names. It then blocks for a change in state to occur on any of the OR'd values contained in dwCurrentState for a maximum blocking time of dwTimeout or forever if INFINITE is used. The new event state will be contained in dwEventState. A status change might be a card insertion or removal event, a change in ATR, etc. This function will block for reader availability if cReaders is equal to zero and rgReaderStates is NULL.

This function reestablishes a connection to a reader that was previously connected to using SCardConnect(). In a multi application environment it is possible for an application to reset the card in shared mode. When this occurs any other application trying to access certain commands will be returned the value SCARD_W_RESET_CARD. When this occurs SCardReconnect() must be called in order to acknowledge that the card was reset and allow it to change it's state accordingly.

This function returns the current status of the reader connected to by hCard. It's friendly name will be stored in szReaderName. pcchReaderLen will be the size of the allocated buffer for szReaderName, while pcbAtrLen will be the size of the allocated buffer for pbAtr. If either of these is too small, the function will return with SCARD_E_INSUFFICIENT_BUFFER and the necessary size in pcchReaderLen and pcbAtrLen. The current state, and protocol will be stored in pdwState and pdwProtocol respectively.

This function sends an APDU to the smart card contained in the reader connected to by SCardConnect(). The card responds from the APDU and stores this response in pbRecvBuffer and it's length in SpcbRecvLength. SSendPci and SRecvPci are structures containing the following: typedef struct { DWORD dwProtocol; // SCARD_PROTOCOL_T0 or SCARD_PROTOCOL_T1 DWORD cbPciLength; // Length of this structure - not used } SCARD_IO_REQUEST;
