# VkPhysicalDeviceMaintenance3Properties(3) Manual Page

## Name

VkPhysicalDeviceMaintenance3Properties - Structure describing descriptor set properties

Loading… please wait.

## C Specification

The `VkPhysicalDeviceMaintenance3Properties` structure is defined as:

    // Provided by VK_VERSION_1_1
    typedef struct VkPhysicalDeviceMaintenance3Properties {
        VkStructureType    sType;
        void*              pNext;
        uint32_t           maxPerSetDescriptors;
        VkDeviceSize       maxMemoryAllocationSize;
    } VkPhysicalDeviceMaintenance3Properties;

or the equivalent

    // Provided by VK_KHR_maintenance3
    typedef VkPhysicalDeviceMaintenance3Properties VkPhysicalDeviceMaintenance3PropertiesKHR;

## Members

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

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

## Description

- `maxPerSetDescriptors` is a maximum number of descriptors (summed over all descriptor types) in a single descriptor set that is guaranteed to satisfy any implementation-dependent constraints on the size of a descriptor set itself. Applications can query whether a descriptor set that goes beyond this limit is supported using vkGetDescriptorSetLayoutSupport.

- `maxMemoryAllocationSize` is the maximum size of a memory allocation that can be created, even if there is more space available in the heap.

If the `VkPhysicalDeviceMaintenance3Properties` structure is included in the `pNext` chain of the VkPhysicalDeviceProperties2 structure passed to vkGetPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceMaintenance3Properties-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_MAINTENANCE_3_PROPERTIES`
