DOS functions setvect, getvect

DOS functions setvect, getvect

[Alvaro de Luna]

Hi,
    I'm trying to transform a DOS driver into a Linux one, but don't
know
    what functions use to replace "setvect" and "getvect", does anybody
    knows?

Thanks,
    Alvaro.

Hi, Device driver structure in Linux is totally different from what you have
in DOS. there is a book named  "Linux device drivers", ISBN: ISBN: 0-596-00008-1
check that out. 
good luck
Masoud

You probably want ...

  request_irq(IRQ_NR, isr_procedure, SA_INTERRUPT, 
                         char_ptr_device_name, void_ptr_to_params).
... and ...

  free_irq(IRQ_NR, void_ptr_to_params);

In Linux, the kernel sets up and tears down 'vectors' for you.
You need to get a book on drivers (modules).

In user-mode, there is no such thing as an interrupt vector because
they will all cause a trap to the kernel, the kernel handles them,
usually by killing the process. In one case only, the kernel
allows user mode int 0x80. This is for kernel services. You
can't "get that vector" and "set a new one".
