All you should have to do is:

        G_CONST_RETURN gchar *text = NULL;

        text = gtk_entry_get_text(GTK_ENTRY(myentry));
        if(text && g_utf8_strlen(text,-1) > 0)
        {
                gint number = -1;

                number = atoi(text);
                g_message("the number is :%d", number);
        }

If you are interested in catching errors based on users entering non numeric
characters, perhaps you should consider either:

        number = g_ascii_strtod(text, &endptr);

or using a GtkSpinButton where only numeric values are excepted:
