## Name

VkPhysicalDevicePCIBusInfoPropertiesEXT - Structure containing PCI bus information of a physical device

Loading… please wait.

## C Specification

The `VkPhysicalDevicePCIBusInfoPropertiesEXT` structure is defined as:

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

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this 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

If the `VkPhysicalDevicePCIBusInfoPropertiesEXT` structure is included in the `pNext` chain of the VkPhysicalDeviceProperties2 structure passed to vkGetPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.

These are properties of the PCI bus information of a physical device.

Valid Usage (Implicit)

- VUID-VkPhysicalDevicePCIBusInfoPropertiesEXT-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_PCI_BUS_INFO_PROPERTIES_EXT`
