Hi all, I was tring to find the start up time of my gtk application .... i am getting negative time. i am putting the code here. please comment on it...
windowA.c
#include <stdio.h>
#include <gtk/gtk.h>
#include <gdk/gdk.h>
#include <sys/time.h>
void callback_winb(GtkWidget *,gpointer);
extern GtkWidget *windowb;
GtkWidget *windowa;
//struct timeval timer(struct timeval);
/* This is a simple call back fuction for closing the window */
void
callback1(GtkWidget *widget,
gpointer data)
{
g_print("Pressed key is: %s\n",(gchar *)data);
gtk_main_quit();
}
int
callback_wina(GtkWidget *widget,
gpointer data)
{
// gtk_widget_hide(windowb);
GtkWidget *boxa;
GtkWidget *buttona;
windowa=gtk_window_new(GTK_WINDOW_TOPLEVEL);
gtk_window_set_title(GTK_WINDOW(windowa),"Window A");
g_signal_connect(G_OBJECT(windowa),"destroy",
G_CALLBACK(callback1),(gpointer)"Close");
g_print("toggling to window b\n");
gtk_container_set_border_width(GTK_CONTAINER(windowa),20);
buttona=gtk_button_new_with_label("Toggle_A");
g_signal_connect(G_OBJECT(buttona),"clicked",
G_CALLBACK(callback_winb),NULL);
gtk_container_add(GTK_CONTAINER(windowa),buttona);
gtk_widget_show_all(windowa);
}
int
main(int argc,
char *argv[])
{
struct timeval tp,tn;
long times;
gettimeofday(&tp,NULL);
printf("tp.sec: %ld\n",tp.tv_sec);
printf("tp.usec: %ld\n",tp.tv_usec);
gtk_init(&argc,&argv);
callback_wina(NULL,(gpointer)20);
gtk_main();
gettimeofday(&tn,NULL);
printf("tn.sec: %ld\n",tn.tv_sec);
printf("tn.usec: %ld\n",tn.tv_usec);
times=((tn.tv_sec - tp.tv_sec)/1000000)+
(tn.tv_usec - tp.tv_usec);
printf("startup time : %ld\n ",times);
return 0;
}
windowB.c
