static int ProcessCommonChannelRequest(uint32_t *pdwClientID)
Accepts a Client connection.
INTERNAL int32_t ListenExistingSocket(int fd)
Acquires a socket passed in from systemd.
This defines some structures and #defines to be used over the transport layer.
INTERNAL int32_t InitializeSocket(void)
Prepares the communication channel used by the server to talk to the clients.
static int commonSocket
Socket to a file, used for clients-server comminication.
This keeps a list of defines for pcsc-lite.
INTERNAL int32_t ProcessEventsServer(uint32_t *pdwClientID)
Looks for messages sent by clients.
This handles smart card reader communications.
