# VkPhysicalDevicePCIBusInfoPropertiesEXT(3) Manual Page

## Name

VkPhysicalDevicePCIBusInfoPropertiesEXT - Structure containing PCI bus information of a physical device

## C Specification

To query the PCI bus information of a physical device, add a VkPhysicalDevicePCIBusInfoPropertiesEXT structure to the `pNext` chain of the VkPhysicalDeviceProperties2 structure. The `VkPhysicalDevicePCIBusInfoPropertiesEXT` structure is defined as:

    typedef struct VkPhysicalDevicePCIBusInfoPropertiesEXT {
        VkStructureType    sType;
        void*              pNext;
        uint32_t           pciDomain;
        uint32_t           pciBus;
        uint32_t           pciDevice;
        uint32_t           pciFunction;
    } VkPhysicalDevicePCIBusInfoPropertiesEXT;

## Members

- `sType` is the type of this structure.

- `pNext` is `NULL` or a pointer to an extension-specific structure.

- `pciDomain` is the PCI bus domain.

- `pciBus` is the PCI bus identifier.

- `pciDevice` is the PCI device identifier.

- `pciFunction` is the PCI device function identifier.

## Description

Valid Usage (Implicit)

- `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_PCI_BUS_INFO_PROPERTIES_EXT`
