## Name

VkPhysicalDeviceDescriptorPoolOverallocationFeaturesNV - Structure describing feature to allow descriptor pool overallocation

Loading… please wait.

## C Specification

The `VkPhysicalDeviceDescriptorPoolOverallocationFeaturesNV` structure is defined as:

    // Provided by VK_NV_descriptor_pool_overallocation
    typedef struct VkPhysicalDeviceDescriptorPoolOverallocationFeaturesNV {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           descriptorPoolOverallocation;
    } VkPhysicalDeviceDescriptorPoolOverallocationFeaturesNV;

## Members

This structure describes the following feature:

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

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

- `descriptorPoolOverallocation` indicates that the implementation allows the application to opt into descriptor pool overallocation by creating the descriptor pool with `VK_DESCRIPTOR_POOL_CREATE_ALLOW_OVERALLOCATION_SETS_BIT_NV` and/or `VK_DESCRIPTOR_POOL_CREATE_ALLOW_OVERALLOCATION_POOLS_BIT_NV` flags.

## Description

If the `VkPhysicalDeviceDescriptorPoolOverallocationFeaturesNV` 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. `VkPhysicalDeviceDescriptorPoolOverallocationFeaturesNV` can also be used in the `pNext` chain of VkDeviceCreateInfo to selectively enable these features.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceDescriptorPoolOverallocationFeaturesNV-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_DESCRIPTOR_POOL_OVERALLOCATION_FEATURES_NV`
