Calling function w/ multiple parameters

[ajam <ajam erols com>]

Continuing my previous message, I opted to use a pointer to a
structure to pass all the parameters to my function through
the use of the fourth argument of "gtk_signal_connect()",
which is actually expecting a "gpointer".  Well, it doesn't
work.  No surprise here.  Is there a Macro or other method
in order to be able to send this pointer to the function?

Thanks, ajam.
