C Specification
To query the extensions available to a given physical device, call:
// Provided by VK_VERSION_1_0
VkResult vkEnumerateDeviceExtensionProperties(
VkPhysicalDevice physicalDevice,
const char* pLayerName,
uint32_t* pPropertyCount,
VkExtensionProperties* pProperties);
Parameters
-
physicalDevice
is the physical device that will be queried. -
pLayerName
is eitherNULL
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 eitherNULL
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.
Implementations must not advertise any pair of extensions that cannot be enabled together due to behavioral differences, or any extension that cannot be enabled against the advertised version.
Implementations claiming support for the Roadmap 2022
profile must advertise the VK_KHR_global_priority
extension in
pProperties
.
