C++ (Cpp) IRQHANDLER Examples

Example #1

File: pcan_pci_linux.c Project: AaronMR/AaronMR_Robotic_Stack

// a special frame around the default irq handler
static irqreturn_t IRQHANDLER(pcan_pci_irqhandler, int irq, void *dev_id, struct pt_regs *regs)
{
  struct pcandev *dev = (struct pcandev *)dev_id;
  int ret;

  #if LINUX_VERSION_CODE >= KERNEL_VERSION(2,5,0)
  ret = IRQHANDLER(sja1000_irqhandler, irq, dev_id, regs);
  #else
  IRQHANDLER(sja1000_irqhandler, irq, dev_id, regs);
  ret = 0; // supress warning about unused variable
  #endif

  pcan_pci_clear_stored_interrupt(dev);

  return PCAN_IRQ_RETVAL(ret);
}

Example #2

//----------------------------------------------------------------------------

  // irq-level until at least all devices are one time idle.
