XW_CALLBACK acallback CallBack Routine Address (Can be NULL)
XW_USERDATA auserdata Associated UserData Address (Can be NULL)
Associate an CallBack routine to the window
This Routine is call when any Event of type EVENTTYPE is
received at Xw_wait_event time
NOTE than if callback is NULL ,this remove the corresponding
event of type EVENTTYPE .
Callback programming example :
{
static XW_CALLBACK any_callback(event,data)
XW_EVENT *event ;
XW_USERDATA *data ;
{
printf(" This trap ANY Xw_event of type %d from Ext_window %x\n",
event->type,event->any.awindow);
}
Xw_set_event(ext_window,XW_ALLEVENT,any_callback,user_data) ;
}
Returns XW_ERROR if Extended Window address is undefined
Returns XW_SUCCESS if successful
