Newbie with probs Help!

["Nicolas Raitman" <new_world radar com ar>]

Hi to all... for you who do not remember I was having some problems in
passing arguments to callback functions. I will state the problem clearer
than before. Suppose that I have a label which will display the contents of
an entry when a button is clicked, simple isn't it? Well... I have done the
following, please look at the comments...

Thanks a lot, really and please HELP!

#include <gtk/gtk.h>

gint destroy (void)
{
    gtk_main_quit();
    return(FALSE);
}

void showname (GtkButton * button, GtkWidget * label)
{

    /* Here I have the problem. How can I acces the label and the textbox at
the same time?? */
    gtk_label_set_text(GTK_LABEL(label), /* I should put here the contents
of the entry, how can I do that? I mean, I have access to the label, but not
to the text... */ );
    gtk_widget_show(label);
    return;
