Detailed Description

This is the main pcscd daemon.

The function main() starts up the communication environment.
Then an endless loop is calld to look for Client connections. For each Client connection a call to CreateContextThread() is done.

Function Documentation

◆ signal_thread()

static void* signal_thread ( void *  arg)
static

thread dedicated to handle signals

a signal handler can not call any function. See signal(7) for a list of function that are safe to call from a signal handler. The functions syslog(), gettimeofday() and remove() are NOT safe.

Definition at line 175 of file pcscdaemon.c.

◆ SVCServiceRunLoop()

static void SVCServiceRunLoop ( void  )
static

The Server's Message Queue Listener function.

An endless loop calls the function ProcessEventsServer() to check for messages sent by clients. If the message is valid, CreateContextThread() is called to serve this request.

Definition at line 104 of file pcscdaemon.c.

Variable Documentation

◆ AutoExit

char AutoExit = FALSE

Represents an Application Context on the Server side.

An Application Context contains Channels (hCard).
