[cc65] Interrupts howto?

Hi,

I have tried to understand how callirq and condes should go together
but it would be really helpful to get a small description of how I should
do this.

The way I used to do this was to do something like:

_InitIRQ:
  sets the address of __IRQ to 0xfffe
  rts

_install_irq:
  adds a vector to the _irqvecs table
  rts

__IRQ:
  save registers
  clear interrupts
  set X to index to an interrupt table
  jsr __IRQ5
  restore registers
  rti
__IRQ5: jmp (_irqvecs),x

If I understand correctly I can use CONDES to put my addresses into
the _irqvecs table during the linking phase somehow.

Thanks for any help,

Karri
