C Specification

To query the extensions available to a given physical device, call:

VkResult vkEnumerateDeviceExtensionProperties(
    VkPhysicalDevice                            physicalDevice,
    const char*                                 pLayerName,
    uint32_t*                                   pPropertyCount,
    VkExtensionProperties*                      pProperties);

Parameters

  • physicalDevice is the physical device that will be queried.

  • pLayerName is either NULL or a pointer to a null-terminated UTF-8 string naming the layer to retrieve extensions from.

  • pPropertyCount is a pointer to an integer related to the number of extension properties available or queried, and is treated in the same fashion as the vkEnumerateInstanceExtensionProperties::pPropertyCount parameter.

  • pProperties is either NULL or a pointer to an array of VkExtensionProperties structures.

Description

When pLayerName parameter is NULL, only extensions provided by the Vulkan implementation or by implicitly enabled layers are returned. When pLayerName is the name of a layer, the device extensions provided by that layer are returned.

Valid Usage (Implicit)
  • physicalDevice must be a valid VkPhysicalDevice handle

  • If pLayerName is not NULL, pLayerName must be a null-terminated UTF-8 string

  • pPropertyCount must be a valid pointer to a uint32_t value

  • If the value referenced by pPropertyCount is not 0, and pProperties is not NULL, pProperties must be a valid pointer to an array of pPropertyCount VkExtensionProperties structures

Return Codes
On success, this command returns
  • VK_SUCCESS

  • VK_INCOMPLETE

On failure, this command returns
  • VK_ERROR_OUT_OF_HOST_MEMORY

  • VK_ERROR_OUT_OF_DEVICE_MEMORY

  • VK_ERROR_LAYER_NOT_PRESENT
