[fpc-devel]Calling previous INTroutine

[Aleksey V. Vaneev]

Hello,

  I've encountered a problem with calling previous interrupt routine
  in my handler. I'm doing this under go32v2. I install handler with
  set_pm_interrupt(), and before that I do get_pm_interrupt().
  Everything works, but when I chain previous handler using the
  following construct:

  asm
    pushfd
    call qword ptr [OldHandler]
  end;

  It just traps. What can I do? (I'm working with system timer ISR).

Best regards,
 Aleksey                          mailto:picoder at sbis.komi.ru
