Description:

The ado_pci structure describes the PCI card selected by ado_pci_device(). The members include:

index

Index of the device

id

The connection handle to the PCI server. See pci_attach() in the QNX Library Reference.

handle

A handle that you can use to identify the PCI device. See pci_attach_device() in the QNX Library Reference.

vendor

Vendor ID.

device

Device ID.

subsystem

Subsystem ID.

subsysvendor

Subsystem vendor ID.

devfunc

Device/function ID.

revision

Device revision

class_protocol

Class protocol.

irq

Interrupt number.

bmstr

Translation from the CPU busmaster address to the PCI busmaster address.

iobase[6]

CPU base address.

iolen[6]

Size of the base address aperture into the board.

class

Class code.

Classification:

QNX Neutrino
