Hi Göran and Olexiy,
Göran:
I have tried exactly the same way you suggested. The following are the sequence of statements that I am using
int get_data(gpointer data,gint source,GdkInputCondition condition)
{
char buf[100];
fd = source;
read(fd,buff,strlen(buf)*sizeof(char));
printf("%s",buf);
}
in my button handler
static void button_clicked(GtkWidget widget,gpoitner data)
{
sock = socket();
bind();
printf("waiting to receive data\n");
gdk_input_add(sock,GDK_INPUT_READ,(GdkInputFunction)get_data,&cmdinfo);
}
When I execute the above code, the program just keeps waiting for the data printing "waiting to receive data". Even if the other host sends the data this program wont receive it.

Button handler is a callback on "clicked" signal, isn't it ?

You mean the "callback is never executed" or "callback is executed but
you code in callback isn't working" ?My callback works but the receiving statement (recvfrom) would ever receive any data. It just keeps waiting on and on.

So your code have to work with gtk too...
