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;

or the equivalent

// Provided by VK_KHR_variable_pointers
typedef VkPhysicalDeviceVariablePointersFeatures VkPhysicalDeviceVariablePointersFeaturesKHR;


This structure describes the following features:


  • sType is the type of this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • variablePointersStorageBuffer specifies whether the implementation supports the SPIR-V VariablePointersStorageBuffer capability. When this feature is not enabled, shader modules must not declare the SPV_KHR_variable_pointers extension or the VariablePointersStorageBuffer capability.

  • variablePointers specifies whether the implementation supports the SPIR-V VariablePointers capability. When this feature is not enabled, shader modules must not declare the VariablePointers 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. VkPhysicalDeviceVariablePointersFeatures can also be used in the pNext chain of VkDeviceCreateInfo to selectively enable these features.

Valid Usage
  • VUID-VkPhysicalDeviceVariablePointersFeatures-variablePointers-01431
    If variablePointers is enabled then variablePointersStorageBuffer must also be enabled

Valid Usage (Implicit)
  • VUID-VkPhysicalDeviceVariablePointersFeatures-sType-sType
