Function Documentation

void gs_button_press_event (  GtkWidget *    widget, gpointer    data )

This function is called if a button is pressed. Parameters: widget  (GtkWidget *) pointer to affected object (button). event  (GdkEventMotion *) pointer to structure which describes the event.

void gs_da_expose_event (  GtkWidget *    widget, gpointer    data )

This function is called by gtk if the drawing area (da) needs to be redrawn. For example if it becomes visible. Parameters: widget  (GtkWidget *) pointer to affected object (in this case the drawing area). data  (gpointer) pointer to additional data from gtk.

void gs_delete_event (  GtkWidget *    widget, gpointer    data )

This function will be called be gtk when the window gets a closing command, it makes sure that the interface is down and the program is finished. Parameters: widget  (GtkWidget *) pointer to affected object (for example: window). data  (gpointer) pointer to additional data from gtk.

linemonitor_exception (  char *    server, int    port, int    type )

Exception function for linemonitor_server(), print exception code and meaning on the screen and initiate appropriate actions if necessary. See linemonitor_server() API.

int main (  int    argc, char *    argv[] )

test0001sockts: see test0001sockts.c.

thread_wait_for_linemonitor (    )

Start the linemonitor_server() -- waiting for a connection in a background-thread. This has to be a thread because otherwise the system would block. It would wait for a connection while it is supposed to connect itself.
