[INIMSS] How to use "gpointer user_data" in the signals?

[Dino Cherian K <inimss yahoo com>]

Hi

Anybody please help.

How can i use "gpointer user_data" that is got by the signal handlers?. Where 
can I set the data?

I was looking for some way to associate some data structure to a window or 
widget like the one done by gtk_clist_set_row_data and gtk_clist_set_row_data.

Thanks
