VkPhysicalDeviceMaintenance4Properties(3)

# VkPhysicalDeviceMaintenance4Properties(3) Manual Page

## Name

VkPhysicalDeviceMaintenance4Properties - Structure describing various implementation-defined properties introduced with VK_KHR_maintenance4

## C Specification

The `VkPhysicalDeviceMaintenance4Properties` structure is defined as:

    // Provided by VK_VERSION_1_3
    typedef struct VkPhysicalDeviceMaintenance4Properties {
        VkStructureType    sType;
        void*              pNext;
        VkDeviceSize       maxBufferSize;
    } VkPhysicalDeviceMaintenance4Properties;

    // Provided by VK_KHR_maintenance4
    // Equivalent to VkPhysicalDeviceMaintenance4Properties
    typedef VkPhysicalDeviceMaintenance4Properties VkPhysicalDeviceMaintenance4PropertiesKHR;

## Members

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

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

## Description

- `maxBufferSize` is the maximum size `VkBuffer` that can be created.

If the `VkPhysicalDeviceMaintenance4Properties` 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-VkPhysicalDeviceMaintenance4Properties-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_MAINTENANCE_4_PROPERTIES

Structure Chaining

Extends the structure

  - VkPhysicalDeviceProperties2
