Macros
#define	PCSCLITE_SHARING_LAST_CONTEXT   1
	One application is using the reader.
#define	PCSCLITE_SHARING_NO_CONTEXT   0
	No application is using the reader.
#define	PCSCLITE_SHARING_EXCLUSIVE_CONTEXT   -1
	Reader used in exclusive mode.
#define	READER_NOT_INITIALIZED   (MAX_ATR_SIZE+1)
	Special value to indicate that power up has not yet happen This is used to auto start mode to wait until the reader is ready and the (possible) card has been powered up.
