Hello,

For my PCI add-on card,in Qnx environment,I could able to get
the memory base address as well as the register base addresses by
using CA_PCI functions.

But whenever I try to get interrupt Line,am getting some 129.Is it the
valid Irq number.
When I tried to see my PCI card by using SHOW_PCI,Icould not see my
card in the listed PCI cards.But thru _CA_Find_PCI_Device(),I could
get bus number and devicefunc number.

What could be the problem regarding Irq number?Can I use any of the
unused Irq number between 0 to 15?

No - you have to use the IRQ which the board is setup to through the PCI
plug and play. Try to run following command and see if it reports the
correct IRQ back:

pci -v


If it does then double check your type castings on the IRQ variables.
