LIBRARY ROUTINE

xvw_insert_callback - insert a callback to a GUI object

LIBRARY CALL

void xvw_insert_callback(
   xvobject   object,
   char       *type,
   int	      busy,
   void       (*callback_routine)(xvobject, kaddr, kaddr),
   kaddr      client_data)

INPUT

OUTPUT

none

RETURN VALUE

none

DESCRIPTION

Installs a callback on a GUI object. The only difference between this routine and xvw_add_callback() is that it allows you to specify whether the object should be busied upon invocation of the callback. This is typically used in callbacks that won't take a lot of time, and thus don't want to incur the unnecessary overhead involved with making them "busy".
