Function Documentation

EFI_STATUS EFIAPI PciCapPciIoDeviceInit	(	IN EFI_PCI_IO_PROTOCOL *	PciIo,
		OUT PCI_CAP_DEV **	PciDevice
	)

Create a PCI_CAP_DEV object from an EFI_PCI_IO_PROTOCOL instance. The config space accessors are based upon EFI_PCI_IO_PROTOCOL.Pci.Read() and EFI_PCI_IO_PROTOCOL.Pci.Write().

Parameters

[in]	PciIo	EFI_PCI_IO_PROTOCOL representation of the PCI device.
[out]	PciDevice	The PCI_CAP_DEV object constructed as described above. PciDevice can be passed to the PciCapLib APIs.

Return values

EFI_SUCCESS	PciDevice has been constructed and output.
EFI_OUT_OF_RESOURCES	Memory allocation failed.

VOID EFIAPI PciCapPciIoDeviceUninit

(

IN PCI_CAP_DEV *

PciDevice

)

Free the resources used by PciDevice.

Parameters

[in]

PciDevice

The PCI_CAP_DEV object to free, originally produced by PciCapPciIoDeviceInit().
