This is responsible for client/server communication.
A file based socket (commonSocket
) is used to send/receive only messages among clients and server.
The messages' data are passed throw a memory mapped file: sharedSegmentMsg
.

Definition at line 175 of file winscard_msg.c.
Prepares a communication channel for the client to talk to the server.
This is called by the application to create a socket for local IPC with the server. The socket is associated to the file PCSCLITE_CSOCK_NAME
.
