This function returns a list of currently available readers on the system.

is a pointer to a character string that is allocated by the application. If the application sends mszGroups
and mszReaders
as NULL then this function will return the size of the buffer needed to allocate in pcchReaders
.

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.
