[cc65] simple assembly interrupt handler

Hello All,

    I'm attempting to convert the excellent tutorial assembly program in 
the NES 101 document by Michael Martin to cc65 c.  I think I can get it 
99% there, but I can't seem to do the interrupt handler in c, at least 
according to the cc65 faq.  Here is the interrupt handler code that I 
need to convert.

vblank: jsr scroll'screen
            jsr update'sprite
            jsr react'to'input
   irq:    rti

.advance $FFFA
.word vblank, reset, irq

    As I understand it, $FFFA is the memory address where the interrupt 
looks for the handler to jump to.  In this case, I am mostly interested 
in the vblank isr, as I need to update the video ram buffer during the 
video blank interval.  In the original code, several things are updated 
in the handler by calling the 3 subroutines, but I think if I could just 
set a vblank flag variable in the handler and do the updates in my main 
code loop, that would be fine.  So, if I want to do this, I think I need 
to use a linker config file and a .segment command to place the handler 
address at $FFFA, but I'm not sure how to do that, since I don't know 
how I specify where I want to jump to.  Can someone help me out with a 
bit of example code or something?  Any help is appreciated.

Thanks,
Paul
