But after a second thought--> the very idea of putting the large compression routine in the bridge code now seems awkward to me. since the compression takes time and putting the code in the bridge may be causing high interrupts i now think if i can do the compression stuffs in separate thread/process than in the bridge process itself. but right now i don't know how do i create a separate process/thread, what are the routines that i need to implement for this.. and also how to dispatch control from the bridge process to a new process without blocking. i am looking into these stuffs and hope i find something from the sources but it is getting really difficult ... maybe you people could have something to say, any advice on whether i am doing the right stuffs would be greatly helpful to me .. thanks, kamal __________________________________________________ Do You Yahoo!?
