C Specification
The VkPhysicalDeviceVariablePointersFeatures
structure is defined as:
// Provided by VK_VERSION_1_1
typedef struct VkPhysicalDeviceVariablePointersFeatures {
VkStructureType sType;
void* pNext;
VkBool32 variablePointersStorageBuffer;
VkBool32 variablePointers;
} VkPhysicalDeviceVariablePointersFeatures;
// Provided by VK_VERSION_1_1
typedef VkPhysicalDeviceVariablePointersFeatures VkPhysicalDeviceVariablePointerFeatures;
or the equivalent
// Provided by VK_KHR_variable_pointers
typedef VkPhysicalDeviceVariablePointersFeatures VkPhysicalDeviceVariablePointersFeaturesKHR;
// Provided by VK_KHR_variable_pointers
typedef VkPhysicalDeviceVariablePointersFeatures VkPhysicalDeviceVariablePointerFeaturesKHR;
Members
This structure describes the following features:
-
sType
is a VkStructureType value identifying this structure. -
pNext
isNULL
or a pointer to a structure extending this structure.
Description
-
variablePointersStorageBuffer
specifies whether the implementation supports the SPIR-VVariablePointersStorageBuffer
capability. When this feature is not enabled, shader modules must not declare theSPV_KHR_variable_pointers
extension or theVariablePointersStorageBuffer
capability. -
variablePointers
specifies whether the implementation supports the SPIR-VVariablePointers
capability. When this feature is not enabled, shader modules must not declare theVariablePointers
capability.
If the VkPhysicalDeviceVariablePointersFeatures
structure is included in the pNext
chain of the
VkPhysicalDeviceFeatures2 structure passed to
vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each
corresponding feature is supported.
If the application wishes to use a VkDevice with any features
described by VkPhysicalDeviceVariablePointersFeatures
, it must add an instance of the structure,
with the desired feature members set to VK_TRUE
, to the pNext
chain of VkDeviceCreateInfo when creating the VkDevice.
