Detailed Description

This is the main pcscd daemon.

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

at_exit()

static void at_exit ( void  )

Definition at line 805 of file pcscdaemon.c.

clean_temp_files()

static void clean_temp_files ( void  )

static

Definition at line 829 of file pcscdaemon.c.

main()

int main	(	int	argc,
		char **	argv
	)

Definition at line 255 of file pcscdaemon.c.

print_usage()

static void print_usage ( char const * const  progname )

static

Definition at line 869 of file pcscdaemon.c.

print_version()

static void print_version ( void  )

static

Definition at line 856 of file pcscdaemon.c.

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 174 of file pcscdaemon.c.

signal_trap()

static void signal_trap ( int  sig )

static

Definition at line 847 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.
